    /**
      An `Ember.Binding` connects the properties of two objects so that whenever

      ## Automatic Creation of Bindings with `/^*Binding/`-named Properties

      You do not usually create Binding objects directly but instead describe
      bindings in your class or object definition using automatic binding
      detection.

      Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
      instances. The value of this property should be a string representing a path
      to another object or a custom binding instanced created using Binding helpers
      (see "One Way Bindings"):

      ```
      valueBinding: "MyApp.someController.title"
      ```

      This will create a binding from `MyApp.someController.title` to the `value`
      property of your object instance automatically. Now the two values will be
      kept in sync.

      ## One Way Bindings

      One especially useful binding customization you can use is the `oneWay()`
      helper. This helper tells Ember that you are only interested in
      receiving changes on the object you are binding from. For example, if you
      are binding to a preference and you want to be notified if the preference
      has changed, but your object will not be changing the preference itself, you
      could do:

      ```
      bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
      ```

      This way if the value of `MyApp.preferencesController.bigTitles` changes the
      `bigTitles` property of your object will change also. However, if you
      change the value of your `bigTitles` property, it will not update the
      `preferencesController`.

      One way bindings are almost twice as fast to setup and twice as fast to
      execute because the binding only has to worry about changes to one side.

      You should consider using one way bindings anytime you have an object that
      may be created frequently and you do not intend to change a property; only
      to monitor it for changes (such as in the example above).

      ## Adding Bindings Manually

      All of the examples above show you how to configure a custom binding, but the
      result of these customizations will be a binding template, not a fully active
      Binding instance. The binding will actually become active only when you
      instantiate the object the binding belongs to. It is useful however, to
      understand what actually happens when the binding is activated.

      For a binding to function it must have at least a `from` property and a `to`
      property. The `from` property path points to the object/key that you want to
      bind from while the `to` path points to the object/key you want to bind to.

      When you define a custom binding, you are usually describing the property
      you want to bind from (such as `MyApp.someController.value` in the examples
      above). When your object is created, it will automatically assign the value
      you want to bind `to` based on the name of your binding key. In the
      examples above, during init, Ember objects will effectively call
      something like this on your binding:

      ```javascript
      binding = Ember.Binding.from(this.valueBinding).to("value");
      ```

      This creates a new binding instance based on the template you provide, and
      sets the to path to the `value` property of the new object. Now that the
      binding is fully configured with a `from` and a `to`, it simply needs to be
      connected to become active. This is done through the `connect()` method:

      ```javascript
      binding.connect(this);
      ```

      Note that when you connect a binding you pass the object you want it to be
      connected to. This object will be used as the root for both the from and
      to side of the binding when inspecting relative paths. This allows the
      binding to be automatically inherited by subclassed objects as well.

      Now that the binding is connected, it will observe both the from and to side
      and relay changes.

      If you ever needed to do so (you almost never will, but it is useful to
      understand this anyway), you could manually create an active binding by
      using the `Ember.bind()` helper method. (This is the same method used by
      to setup your bindings on objects):

      ```javascript
      Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
      ```

      Both of these code fragments have the same effect as doing the most friendly
      form of binding creation like so:

      ```javascript
      MyApp.anotherObject = Ember.Object.create({
        valueBinding: "MyApp.someController.value",

        // OTHER CODE FOR THIS OBJECT...
      });
      ```

      Ember's built in binding creation method makes it easy to automatically
      create bindings for you. You should always use the highest-level APIs
      available, even if you understand how it works underneath.

    // COMPUTED PROPERTY
    //

    /**
      A computed property transforms an objects function into a property.

      By default the function backing the computed property will only be called
      once and the result will be cached. You can specify various properties
      that your computed property is dependent on. This will force the cached
      result to be recomputed if the dependencies are modified.

      In the following example we declare a computed property (by calling
      `.property()` on the fullName function) and setup the properties
      dependencies (depending on firstName and lastName). The fullName function
      will be called once (regardless of how many times it is accessed) as long
      as it's dependencies have not been changed. Once firstName or lastName are updated
      any future calls (or anything bound) to fullName will incorporate the new
      values.

      ```javascript
      Person = Ember.Object.extend({
        // these will be supplied by `create`
        firstName: null,
        lastName: null,

        fullName: function() {
          var firstName = this.get('firstName');
          var lastName = this.get('lastName');

         return firstName + ' ' + lastName;
        }.property('firstName', 'lastName')
      });

      var tom = Person.create({
        firstName: 'Tom',
        lastName: 'Dale'
      });

      tom.get('fullName') // 'Tom Dale'
      ```

      You can also define what Ember should do when setting a computed property.
      If you try to set a computed property, it will be invoked with the key and
      value you want to set it to. You can also accept the previous value as the
      third parameter.

      ```javascript

     Person = Ember.Object.extend({
        // these will be supplied by `create`
        firstName: null,
        lastName: null,

        fullName: function(key, value, oldValue) {
          // getter
          if (arguments.length === 1) {
            var firstName = this.get('firstName');
            var lastName = this.get('lastName');

            return firstName + ' ' + lastName;

          // setter
          } else {
            var name = value.split(" ");

            this.set('firstName', name[0]);
            this.set('lastName', name[1]);

            return value;
          }
        }.property('firstName', 'lastName')
      });

      var person = Person.create();
      person.set('fullName', 'Peter Wagenet');
      person.get('firstName') // 'Peter'
      person.get('lastName') // 'Wagenet'

      The purpose of the Ember Instrumentation module is

      for Ember.

      Subscribe to a listener by using `Ember.subscribe`:

      ```javascript
      Ember.subscribe("render", {
        before: function(name, timestamp, payload) {

        },

        after: function(name, timestamp, payload) {

        }
      });
      ```

      If you return a value from the `before` callback, that same
      value will be passed as a fourth parameter to the `after`
      callback.

      Instrument a block of code by using `Ember.instrument`:

      ```javascript
      Ember.instrument("render.handlebars", payload, function() {
        // rendering logic
      }, binding);
      ```

      Event names passed to `Ember.instrument` are namespaced
      by periods, from more general to more specific. Subscribers
      can listen for events by whatever level of granularity they
      are interested in.

      In the above example, the event is `render.handlebars`,
      and the subscriber listened for all events beginning with
      `render`. It would receive callbacks for events named
      `render`, `render.handlebars`, `render.container`, or
      even `render.handlebars.layout`.

      JavaScript (before ES6) does not have a Map implementation. Objects,

      Because Ember has a way to get a unique identifier for every object
      via `Ember.guidFor`, we can implement a performant Map with arbitrary
      keys. Because it is commonly used in low-level bookkeeping, Map is
      implemented as a pure JavaScript object for performance.

      This implementation follows the current iteration of the ES6 proposal for
      maps (http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets),
      with two exceptions. First, because we need our implementation to be pleasant
      on older browsers, we do not use the `delete` name (using `remove` instead).
      Second, as we do not have the luxury of in-VM iteration, we implement a
      forEach method for iteration.

      Map is mocked out to look like an Ember object, so you can do
      `Ember.Map.create()` for symmetry with other Ember classes.

      Note that Mixins are created with `Ember.Mixin.create`, not

      Note that mixins extend a constructor's prototype so arrays and object literals
      defined as properties will be shared amongst objects that implement the mixin.
      If you want to define a property in a mixin that is not shared, you can define
      it either as a computed property or have it be created on initialization of the object.

      ```javascript
      //filters array will be shared amongst any object implementing mixin
      App.Filterable = Ember.Mixin.create({
        filters: Ember.A()
      });

      //filters will be a separate  array for every object implementing the mixin

      NOTE: This is a low-level method used by other parts of the API. You almost
      never want to call this method directly. Instead you should use
      `Ember.mixin()` to define new properties.

      Defines a property on an object. This method works much like the ES5
      `Object.defineProperty()` method except that it can also accept computed
      properties and other special descriptors.

      Normally this method takes only three parameters. However if you pass an
      instance of `Ember.Descriptor` as the third param then you can pass an
      optional value as the fourth parameter. This is often more efficient than
      creating new descriptor hashes for each property.

      ## Examples

      ```javascript
      // ES5 compatible mode
      Ember.defineProperty(contact, 'firstName', {
        writable: true,
        configurable: false,
        enumerable: true,
        value: 'Charles'
      });

      // define a simple property
      Ember.defineProperty(contact, 'lastName', undefined, 'Jolley');

      // define a computed property
      Ember.defineProperty(contact, 'fullName', Ember.computed(function() {
        return this.firstName+' '+this.lastName;
      }).property('firstName', 'lastName'));
      ```

        computed property) or an ES5 descriptor.
        You must provide this or `data` but not both.
      @param {*} [data] something other than a descriptor, that will

      Provides a useful utility for when integrating with non-Ember libraries
      that provide asynchronous callbacks.

      Ember utilizes a run-loop to batch and coalesce changes. This works by
      marking the start and end of Ember-related Javascript execution.

      When using events such as a View's click handler, Ember wraps the event
      handler in a run-loop, but when integrating with non-Ember libraries this
      can be tedious.

      For example, the following is rather verbose but is the correct way to combine
      third-party events and Ember code.

      ```javascript
      var that = this;
      jQuery(window).on('resize', function(){
        run(function(){
          that.handleResize();
        });
      });
      ```

      To reduce the boilerplate, the following can be used to construct a
      run-loop-wrapped callback handler.

      ```javascript
      jQuery(window).on('resize', run.bind(this, this.handleResize));

      Also note that passing an anonymous function to `run.scheduleOnce` will

      scheduling the items multiple times, e.g.:

      ```javascript
      function scheduleIt() {

      run.next(myContext, function() {
        // code to be executed in the next run loop,
        // which will be scheduled after the current one
      });
      ```

      Multiple operations scheduled with `run.next` will coalesce
      into the same later run loop, along with any other operations
      scheduled by `run.later` that expire right around the same
      time that `run.next` operations will fire.

      Note that there are often alternatives to using `run.next`.
      For instance, if you'd like to schedule an operation to happen
      after all DOM element operations have completed within the current
      run loop, you can make use of the `afterRender` run loop queue (added
      by the `ember-views` package, along with the preceding `render` queue
      where all the DOM element operations happen). Example:

      ```javascript
      App.MyCollectionView = Ember.CollectionView.extend({
        didInsertElement: function() {
          run.scheduleOnce('afterRender', this, 'processChildElements');
        },
        processChildElements: function() {
          // ... do something with collectionView's child view
          // elements after they've finished rendering, which
          // can't be done within the CollectionView's
          // `didInsertElement` hook because that gets run
          // before the child elements have been added to the DOM.
        }
      });
      ```

      One benefit of the above approach compared to using `run.next` is
      that you will be able to perform DOM/CSS operations before unprocessed
      elements are rendered to the screen, which may prevent flickering or
      other artifacts caused by delaying processing until after rendering.

      The other major benefit to the above approach is that `run.next`
      introduces an element of non-determinism, which can make things much
      harder to test, due to its reliance on `setTimeout`; it's much harder
      to guarantee the order of scheduled operations when they are scheduled
      outside of the current run loop, i.e. with `run.next`.

      but the action should only be called once when the event is done firing.
      A common example is for scroll events where you only want updates to
      happen once scrolling has ceased.

      ```javascript
        var myFunc = function() { console.log(this.name + ' ran.'); };
        var myContext = {name: 'debounce'};

        run.debounce(myContext, myFunc, 150);

        // less than 150ms passes

        run.debounce(myContext, myFunc, 150);

        // 150ms passes
        // myFunc is invoked with context myContext
        // console logs 'debounce ran.' one time.
      ```

      Immediate allows you to run the function immediately, but debounce
      other calls for this function until the wait time has elapsed. If
      `debounce` is called again before the specified time has elapsed,
      the timer is reset and the entire period must pass again before
      the method can be called again.

      ```javascript
        var myFunc = function() { console.log(this.name + ' ran.'); };
        var myContext = {name: 'debounce'};

        run.debounce(myContext, myFunc, 150, true);

        // console logs 'debounce ran.' one time immediately.
        // 100ms passes

        run.debounce(myContext, myFunc, 150, true);

        // 150ms passes and nothing else is logged to the console and
        // the debouncee is no longer being watched

        run.debounce(myContext, myFunc, 150, true);

        // console logs 'debounce ran.' one time immediately.
        // 150ms passes and nothing else is logged tot he console and
        // the debouncee is no longer being watched

      @deprecated

      In order to store defaults for a class, a prototype may need to create
      a default meta object, which will be inherited by any objects instantiated
      from the class's constructor.

      However, the properties of that meta object are only shallow-cloned,
      so if a property is a hash (like the event system's `listeners` hash),
      it will by default be shared across all instances of that class.

      This method allows extensions to deeply clone a series of nested hashes or
      other complex objects. For instance, the event system might pass
      `['listeners', 'foo:change', 'ember157']` to `prepareMetaPath`, which will
      walk down the keys provided.

      For each key, if the key does not exist, it is created. If it already
      exists and it was inherited from its constructor, the constructor's
      key is cloned.

      You can also pass false for `writable`, which will simply return
      undefined if `prepareMetaPath` discovers any part of the path that
      shared or undefined.

      The object returned from `RSVP.defer` is a plain object with three properties:

      * resolve - a function that causes the `promise` property on this object to
        become fulfilled.

        });

        object.trigger('foo', { name: 'bar' });
        // 'bar' logged to the console
        ```

        @method trigger
        @param {String} eventName name of the event to be triggered
        @param {Any} options optional value to be passed to any event handlers for

          for (var i=0; i<callbacks.length; i++) {
            callback = callbacks[i];

     `RSVP.filter` is similar to JavaScript's native `filter` method, except that it
      waits for all promises to become fulfilled before running the `filterFn` on
      each item in given to `promises`. `RSVP.filter` returns a promise that will
      become fulfilled with the result of running `filterFn` on the values the
      promises become fulfilled with.

      For example:

      ```javascript

      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.resolve(2);
      var promise3 = RSVP.resolve(3);

      var filterFn = function(item){
        return item > 1;
      };

      RSVP.filter(promises, filterFn).then(function(result){
        // result is [ 2, 3 ]
      });
      ```

      If any of the `promises` given to `RSVP.filter` are rejected, the first promise
      that is rejected will be given as an argument to the returned promise's
      rejection handler. For example:

      ```javascript
      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.reject(new Error("2"));
      var promise3 = RSVP.reject(new Error("3"));
      var promises = [ promise1, promise2, promise3 ];

      var filterFn = function(item){
        return item > 1;
      };

      RSVP.filter(promises, filterFn).then(function(array){
        // Code here never runs because there are rejected promises!
      }, function(reason) {
        // reason.message === "2"
      });
      ```

      `RSVP.filter` will also wait for any promises returned from `filterFn`.
      For instance, you may want to fetch a list of users then return a subset
      of those users based on some asynchronous operation:

      ```javascript

      var alice = { name: 'alice' };
      var bob   = { name: 'bob' };
      var users = [ alice, bob ];

      var promises = users.map(function(user){
        return RSVP.resolve(user);
      });

      var filterFn = function(user){
        // Here, Alice has permissions to create a blog post, but Bob does not.
        return getPrivilegesForUser(user).then(function(privs){
          return privs.can_create_blog_post === true;
        });
      };
      RSVP.filter(promises, filterFn).then(function(users){
        // true, because the server told us only Alice can create a blog post.
        users.length === 1;
        // false, because Alice is the only user present in `users`
        users[0] === bob;
      });
      ```

      `RSVP.hash` is similar to `RSVP.all`, but takes an object instead of an array
      for its `promises` argument.

      Returns a promise that is fulfilled when all the given promises have been
      fulfilled, or rejected if any of them become rejected. The returned promise
      is fulfilled with a hash that has the same key names as the `promises` object
      argument. If any of the values in the object are not promises, they will
      simply be copied over to the fulfilled object.

      Example:

      ```javascript
      var promises = {
        myPromise: RSVP.resolve(1),
        yourPromise: RSVP.resolve(2),
        theirPromise: RSVP.resolve(3),

      };

      RSVP.hash(promises).then(function(hash){
        // hash here is an object that looks like:
        // {
        //   myPromise: 1,
        //   yourPromise: 2,
        //   theirPromise: 3,
        //   notAPromise: 4
        // }
      });
      ````

      If any of the `promises` given to `RSVP.hash` are rejected, the first promise
      that is rejected will be given as the reason to the rejection handler.

      Example:

      ```javascript
      var promises = {
        myPromise: RSVP.resolve(1),
        rejectedPromise: RSVP.reject(new Error("rejectedPromise")),
        anotherRejectedPromise: RSVP.reject(new Error("anotherRejectedPromise")),
      };

      RSVP.hash(promises).then(function(hash){
        // Code here never runs because there are rejected promises!
      }, function(reason) {
        // reason.message === "rejectedPromise"
      });
      ```

      An important note: `RSVP.hash` is intended for plain JavaScript objects that
      are just a set of keys and values. `RSVP.hash` will NOT preserve prototype
      chains.

      Example:

      ```javascript
      function MyConstructor(){
        this.example = RSVP.resolve("Example");
      }

      MyConstructor.prototype = {
        protoProperty: RSVP.resolve("Proto Property")
      };

      var myObject = new MyConstructor();

      RSVP.hash(myObject).then(function(hash){
        // protoProperty will not be present, instead you will just have an
        // object that looks like:
        // {
        //   example: "Example"
        // }
        //
        // hash.hasOwnProperty('protoProperty'); // false
        // 'undefined' === typeof hash.protoProperty
      });
      ```

        // reason.message === "2"
      });
      ```

      `RSVP.map` will also wait if a promise is returned from `mapFn`. For example,
      say you want to get all comments from a set of blog posts, but you need
      the blog posts first becuase they contain a url to those comments.

      ```javscript

      var mapFn = function(blogPost){

        // with some comments data
        return getComments(blogPost.comments_url);
      };

      // getBlogPosts does some ajax and returns an RSVP.Promise that is fulfilled

      `RSVP.denodeify` takes a "node-style" function and returns a function that
      will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
      browser when you'd prefer to use promises over using callbacks. For example,
      `denodeify` transforms the following:

      ```javascript
      var fs = require('fs');

      fs.readFile('myfile.txt', function(err, data){
        if (err) return handleError(err);
        handleData(data);
      });
      ```

      into:

      ```javascript
      var fs = require('fs');

      var readFile = RSVP.denodeify(fs.readFile);

      readFile('myfile.txt').then(handleData, handleError);
      ```

      Using `denodeify` makes it easier to compose asynchronous operations instead
      of using callbacks. For example, instead of:

      ```javascript
      var fs = require('fs');
      var log = require('some-async-logger');

      fs.readFile('myfile.txt', function(err, data){
        if (err) return handleError(err);
        fs.writeFile('myfile2.txt', data, function(err){
          if (err) throw err;
          log('success', function(err) {
            if (err) throw err;
          });
        });
      });
      ```

      You can chain the operations together using `then` from the returned promise:

      ```javascript
      var fs = require('fs');
      var denodeify = RSVP.denodeify;
      var readFile = denodeify(fs.readFile);
      var writeFile = denodeify(fs.writeFile);
      var log = denodeify(require('some-async-logger'));

      readFile('myfile.txt').then(function(data){
        return writeFile('myfile2.txt', data);
      }).then(function(){
        return log('SUCCESS');
      }).then(function(){
        // success handler
      }, function(reason){
        // rejection handler
      });
      ```

      @method denodeify

    /**
      Promise objects represent the eventual result of an asynchronous operation. The
      primary way of interacting with a promise is through its `then` method, which
      registers callbacks to receive either a promise’s eventual value or the reason
      why the promise cannot be fulfilled.

      Terminology
      -----------

      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
      - `thenable` is an object or function that defines a `then` method.
      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
      - `exception` is a value that is thrown using the throw statement.
      - `reason` is a value that indicates why a promise was rejected.
      - `settled` the final resting state of a promise, fulfilled or rejected.

      A promise can be in one of three states: pending, fulfilled, or rejected.

      Promises that are fulfilled have a fulfillment value and are in the fulfilled
      state.  Promises that are rejected have a rejection reason and are in the
      rejected state.  A fulfillment value is never a thenable.  Similarly, a
      rejection reason is never a thenable.

      Promises can also be said to *resolve* a value.  If this value is also a
      promise, then the original promise's settled state will match the value's
      settled state.  So a promise that *resolves* a promise that rejects will
      itself reject, and a promise that *resolves* a promise that fulfills will
      itself fulfill.


      Basic Usage:
      ------------

      ```js
      var promise = new Promise(function(resolve, reject) {
        // on success
        resolve(value);

        // on failure
        reject(reason);
      });

      promise.then(function(value) {
        // on fulfillment
      }, function(reason) {
        // on rejection
      });
      ```

      Advanced Usage:
      ---------------

      Promises shine when abstracting away asynchronous interactions such as
      `XMLHttpRequest`s.

      ```js
      function getJSON(url) {
        return new Promise(function(resolve, reject){
          var xhr = new XMLHttpRequest();

          xhr.open('GET', url);
          xhr.onreadystatechange = handler;
          xhr.responseType = 'json';
          xhr.setRequestHeader('Accept', 'application/json');
          xhr.send();

        return values;

    /**
      The primary way of interacting with a promise is through its `then` method,
      which registers callbacks to receive either a promise's eventual value or the
      reason why the promise cannot be fulfilled.

      ```js
      findUser().then(function(user){
        // user is available
      }, function(reason){
        // user is unavailable, and you are given the reason why
      });
      ```

      Chaining
      --------

      The return value of `then` is itself a promise.  This second, "downstream"
      promise is resolved with the return value of the first promise's fulfillment
      or rejection handler, or rejected if the handler throws an exception.

      ```js
      findUser().then(function (user) {
        return user.name;
      }, function (reason) {
        return "default name";
      }).then(function (userName) {
        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
        // will be `"default name"`
      });

      findUser().then(function (user) {
        throw new Error("Found user, but still unhappy");
      }, function (reason) {
        throw new Error("`findUser` rejected and we're unhappy");
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // if `findUser` fulfilled, `reason` will be "Found user, but still unhappy".
        // If `findUser` rejected, `reason` will be "`findUser` rejected and we're unhappy".
      });
      ```
      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.

      ```js
      findUser().then(function (user) {
        throw new PedagogicalException("Upstream error");
      }).then(function (value) {
        // never reached
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // The `PedgagocialException` is propagated all the way down to here
      });
      ```

      Assimilation
      ------------

      Sometimes the value you want to propagate to a downstream promise can only be
      retrieved asynchronously. This can be achieved by returning a promise in the
      fulfillment or rejection handler. The downstream promise will then be pending
      until the returned promise is settled. This is called *assimilation*.

      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // The user's comments are now available
      });
      ```

      If the assimliated promise rejects, then the downstream promise will also reject.

      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // If `findCommentsByAuthor` fulfills, we'll have the value here
      }, function (reason) {
        // If `findCommentsByAuthor` rejects, we'll have the reason here
      });
      ```

      is fulfilled with an array of fulfillment values for the passed promises, or
      rejected with the reason of the first passed promise to be rejected. It casts all
      elements of the passed iterable to promises as it runs this algorithm.

      Example:

    /**
      `RSVP.Promise.cast` coerces its argument to a promise, or returns the

      Example:

      ```javascript
      var promise = RSVP.Promise.resolve(1);
      var casted = RSVP.Promise.cast(promise);

      console.log(promise === casted); // true
      ```

      In the case of a promise whose constructor does not match, it is assimilated.
      The resulting promise will fulfill or reject based on the outcome of the
      promise being casted.

      Example:

      ```javascript
      var thennable = $.getJSON('/api/foo');
      var casted = RSVP.Promise.cast(thennable);

      console.log(thennable === casted); // false
      console.log(casted instanceof RSVP.Promise) // true

      casted.then(function(data) {
        // data is the value getJSON fulfills with
      });
      ```

      In the case of a non-promise, a promise which will fulfill with that value is
      returned.

      Example:

      ```javascript
      var value = 1; // could be a number, boolean, string, undefined...
      var casted = RSVP.Promise.cast(value);

      console.log(value === casted); // false
      console.log(casted instanceof RSVP.Promise) // true

      casted.then(function(val) {
        val === value // => true
      });
      ```

      `RSVP.Promise.cast` is similar to `RSVP.Promise.resolve`, but `RSVP.Promise.cast` differs in the
      following ways:

      * `RSVP.Promise.cast` serves as a memory-efficient way of getting a promise, when you
      have something that could either be a promise or a value. RSVP.resolve

      `RSVP.Promise.race` returns a new promise which is settled in the same way as the
      first passed promise to settle.

      Example:

      ```javascript
      var promise1 = new RSVP.Promise(function(resolve, reject){
        setTimeout(function(){
          resolve("promise 1");
        }, 200);
      });

      var promise2 = new RSVP.Promise(function(resolve, reject){
        setTimeout(function(){
          resolve("promise 2");
        }, 100);
      });

      RSVP.Promise.race([promise1, promise2]).then(function(result){
        // result === "promise 2" because it was resolved before promise1
        // was resolved.
      });
      ```

      `RSVP.Promise.race` is deterministic in that only the state of the first
      settled promise matters. For example, even if other promises given to the
      `promises` array argument are resolved, but the first settled promise has
      become rejected before the other promises became fulfilled, the returned
      promise will become rejected:

      ```javascript
      var promise1 = new RSVP.Promise(function(resolve, reject){
        setTimeout(function(){
          resolve("promise 1");
        }, 200);
      });

      var promise2 = new RSVP.Promise(function(resolve, reject){
        setTimeout(function(){
          reject(new Error("promise 2"));
        }, 100);
      });

      RSVP.Promise.race([promise1, promise2]).then(function(result){
        // Code here never runs
      }, function(reason){
        // reason.message === "promise2" because promise 2 became rejected before
        // promise 1 became fulfilled
      });
      ```

      An example real-world use case is implementing timeouts:

      ```javascript
      RSVP.Promise.race([ajax('foo.json'), timeout(5000)])
      ```

      @method race
      @param {Array} promises array of promises to observe
      @param {String} label optional string for describing the promise returned.
      Useful for tooling.

      `RSVP.rethrow` will rethrow an error on the next turn of the JavaScript event
      loop in order to aid debugging.

      Promises A+ specifies that any exceptions that occur with a promise must be
      caught by the promises implementation and bubbled to the last handler. For
      this reason, it is recommended that you always specify a second rejection
      handler function to `then`. However, `RSVP.rethrow` will throw the exception
      outside of the promise, so it bubbles up to your console if in the browser,
      or domain/cause uncaught exception in Node. `rethrow` will also throw the
      error again so the error can be handled by the promise per the spec.

      ```javascript
      function throws(){
        throw new Error('Whoops!');
      }

      var promise = new RSVP.Promise(function(resolve, reject){
        throws();

        // Code here doesn't run because the promise became rejected due to an
        // error!
      }, function (err){
        // handle the error here
      });
      ```

      The 'Whoops' error will be thrown on the next turn of the event loop
      and you can watch for it in your console. You can also handle it using a
      rejection handler given to `.then` or `.catch` on the returned promise.

        The default behaviour is for lookup to return a singleton instance.
        The singleton is scoped to the container, allowing multiple containers
        to all have their own locally scoped singletons.

        ```javascript
        var container = new Container();
        container.register('api:twitter', Twitter);

        var twitter = container.lookup('api:twitter');

        var twitter2 = container.lookup('api:twitter');
        twitter instanceof Twitter; // => true

        twitter === twitter2; //=> true
        ```

        If singletons are not wanted an optional flag can be provided at lookup.

        ```javascript
        var container = new Container();
        container.register('api:twitter', Twitter);

        var twitter = container.lookup('api:twitter', { singleton: false });

    /**
      Creates a computed property which operates on dependent arrays and
      is updated with "one at a time" semantics. When items are added or
      removed from the dependent array(s) an array computed only operates
      on the change instead of re-evaluating the entire array. This should
      return an array, if you'd like to use "one at a time" semantics and
      compute some value other then an array look at
      `Ember.reduceComputed`.

      If there are more than one arguments the first arguments are
      considered to be dependent property keys. The last argument is
      required to be an options object. The options object can have the
      following three properties.

      `initialize` - An optional initialize function. Typically this will be used
      to set up state on the instanceMeta object.

      `removedItem` - A function that is called each time an element is
      removed from the array.

      `addedItem` - A function that is called each time an element is
      added to the array.


      The `initialize` function has the following signature:

      ```javascript
       function (array, changeMeta, instanceMeta)
      ```

      `array` - The initial value of the arrayComputed, an empty array.

      `changeMeta` - An object which contains meta information about the
      computed. It contains the following properties:

         - `property` the computed property
         - `propertyName` the name of the property on the object

      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.


      The `removedItem` and `addedItem` functions both have the following signature:

      ```javascript
      function (accumulatedValue, item, changeMeta, instanceMeta)
      ```

      `accumulatedValue` - The value returned from the last time
      `removedItem` or `addedItem` was called or an empty array.

      `item` - the element added or removed from the array

      `changeMeta` - An object which contains meta information about the
      change. It contains the following properties:

        - `property` the computed property
        - `propertyName` the name of the property on the object
        - `index` the index of the added or removed item
        - `item` the added or removed item: this is exactly the same as
          the second arg
        - `arrayChanged` the array that triggered the change. Can be
          useful when depending on multiple arrays.

      For property changes triggered on an item property change (when
      depKey is something like `[email protected]`),
      `changeMeta` will also contain the following property:

        - `previousValues` an object whose keys are the properties that changed on
        the item, and whose values are the item's previous values.

      `previousValues` is important Ember coalesces item property changes via
      Ember.run.once. This means that by the time removedItem gets called, item has
      the new values, but you may need the previous value (eg for sorting &
      filtering).

      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.

      The `removedItem` and `addedItem` functions should return the accumulated
      value. It is acceptable to not return anything (ie return undefined)
      to invalidate the computation. This is generally not a good idea for
      arrayComputed but it's used in eg max and min.

      Example

      ```javascript
      Ember.computed.map = function(dependentKey, callback) {
        var options = {
          addedItem: function(array, item, changeMeta, instanceMeta) {
            var mapped = callback(item);
            array.insertAt(changeMeta.index, mapped);
            return array;
          },
          removedItem: function(array, item, changeMeta, instanceMeta) {
            array.removeAt(changeMeta.index, 1);
            return array;
          }
        };

        return Ember.arrayComputed(dependentKey, options);
      };
      ```

      @method arrayComputed

    /**
      Creates a computed property which operates on dependent arrays and
      is updated with "one at a time" semantics. When items are added or
      removed from the dependent array(s) a reduce computed only operates
      on the change instead of re-evaluating the entire array.

      If there are more than one arguments the first arguments are
      considered to be dependent property keys. The last argument is
      required to be an options object. The options object can have the
      following four properties:

      `initialValue` - A value or function that will be used as the initial
      value for the computed. If this property is a function the result of calling
      the function will be used as the initial value. This property is required.

      `initialize` - An optional initialize function. Typically this will be used
      to set up state on the instanceMeta object.

      `removedItem` - A function that is called each time an element is removed
      from the array.

      `addedItem` - A function that is called each time an element is added to
      the array.


      The `initialize` function has the following signature:

      ```javascript
       function (initialValue, changeMeta, instanceMeta)
      ```

      `initialValue` - The value of the `initialValue` property from the
      options object.

      `changeMeta` - An object which contains meta information about the
      computed. It contains the following properties:

         - `property` the computed property
         - `propertyName` the name of the property on the object

      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.


      The `removedItem` and `addedItem` functions both have the following signature:

      ```javascript
      function (accumulatedValue, item, changeMeta, instanceMeta)
      ```

      `accumulatedValue` - The value returned from the last time
      `removedItem` or `addedItem` was called or `initialValue`.

      `item` - the element added or removed from the array

      `changeMeta` - An object which contains meta information about the
      change. It contains the following properties:

        - `property` the computed property
        - `propertyName` the name of the property on the object
        - `index` the index of the added or removed item
        - `item` the added or removed item: this is exactly the same as
          the second arg
        - `arrayChanged` the array that triggered the change. Can be
          useful when depending on multiple arrays.

      For property changes triggered on an item property change (when
      depKey is something like `[email protected]`),
      `changeMeta` will also contain the following property:

        - `previousValues` an object whose keys are the properties that changed on
        the item, and whose values are the item's previous values.

      `previousValues` is important Ember coalesces item property changes via
      Ember.run.once. This means that by the time removedItem gets called, item has
      the new values, but you may need the previous value (eg for sorting &
      filtering).

      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.

      The `removedItem` and `addedItem` functions should return the accumulated
      value. It is acceptable to not return anything (ie return undefined)
      to invalidate the computation. This is generally not a good idea for
      arrayComputed but it's used in eg max and min.

      Note that observers will be fired if either of these functions return a value
      that differs from the accumulated value.  When returning an object that
      mutates in response to array changes, for example an array that maps
      everything from some other array (see `Ember.computed.map`), it is usually
      important that the *same* array be returned to avoid accidentally triggering observers.

      Example

      ```javascript
      Ember.computed.max = function (dependentKey) {
        return Ember.reduceComputed(dependentKey, {
          initialValue: -Infinity,

          addedItem: function (accumulatedValue, item, changeMeta, instanceMeta) {
            return Math.max(accumulatedValue, item);
          },

          removedItem: function (accumulatedValue, item, changeMeta, instanceMeta) {
            if (item < accumulatedValue) {
              return accumulatedValue;
            }
          }
        });
      };
      ```

      Dependent keys may refer to `@this` to observe changes to the object itself,
      which must be array-like, rather than a property of the object.  This is
      mostly useful for array proxies, to ensure objects are retrieved via
      `objectAtContent`.  This is how you could sort items by properties defined on an item controller.

      Example

      ```javascript
      App.PeopleController = Ember.ArrayController.extend({
        itemController: 'person',

        sortedPeople: Ember.computed.sort('@[email protected]', function(personA, personB) {
          // `reversedName` isn't defined on Person, but we have access to it via
          // the item controller App.PersonController.  If we'd used
          // `[email protected]` above, we would be getting the objects
          // directly and not have access to `reversedName`.
          //
          var reversedNameA = get(personA, 'reversedName'),
              reversedNameB = get(personB, 'reversedName');

          return Ember.compare(reversedNameA, reversedNameB);
        })
      });

      App.PersonController = Ember.ObjectController.extend({
        reversedName: function () {
          return reverse(get(this, 'name'));
        }.property('name')
      })
      ```

      Dependent keys whose values are not arrays are treated as regular
      dependencies: when they change, the computed property is completely
      recalculated.  It is sometimes useful to have dependent arrays with similar
      semantics.  Dependent keys which end in `.[]` do not use "one at a time"
      semantics.  When an item is added or removed from such a dependency, the
      computed property is completely recomputed.

      When the computed property is completely recomputed, the `accumulatedValue`
      is discarded, it starts with `initialValue` again, and each item is passed
      to `addedItem` in turn.

      Example

      ```javascript
      Ember.Object.extend({
        // When `string` is changed, `computed` is completely recomputed.
        string: 'a string',

        // When an item is added to `array`, `addedItem` is called.
        array: [],

    /**
      A computed property which returns a new array with all the
      properties from the first dependent array sorted based on a property
      or sort function.

      The callback method you provide should have the following signature:

      ```javascript
      function(itemA, itemB);
      ```

      - `itemA` the first item to compare.
      - `itemB` the second item to compare.

      This function should return negative number (e.g. `-1`) when `itemA` should come before
      `itemB`. It should return positive number (e.g. `1`) when `itemA` should come after
      `itemB`. If the `itemA` and `itemB` are equal this function should return `0`.

      Therefore, if this function is comparing some numeric values, simple `itemA - itemB` or
      `itemA.get( 'foo' ) - itemB.get( 'foo' )` can be used instead of series of `if`.

      Example

      ```javascript
      var ToDoList = Ember.Object.extend({
        // using standard ascending sort
        todosSorting: ['name'],
        sortedTodos: Ember.computed.sort('todos', 'todosSorting'),

        // using descending sort
        todosSortingDesc: ['name:desc'],
        sortedTodosDesc: Ember.computed.sort('todos', 'todosSortingDesc'),

        // using a custom sort function
        priorityTodos: Ember.computed.sort('todos', function(a, b){
          if (a.priority > b.priority) {
            return 1;
          } else if (a.priority < b.priority) {

    /**
      `Ember.ArrayController` provides a way for you to publish a collection of
      objects so that you can easily bind to the collection from a Handlebars
      `#each` helper, an `Ember.CollectionView`, or other controllers.

      The advantage of using an `ArrayController` is that you only have to set up
      your view bindings once; to change what's displayed, simply swap out the
      `model` property on the controller.

      For example, imagine you wanted to display a list of items fetched via an XHR
      request. Create an `Ember.ArrayController` and set its `model` property:

      ```javascript
      MyApp.listController = Ember.ArrayController.create();

      $.get('people.json', function(data) {
        MyApp.listController.set('model', data);
      });
      ```

      Then, create a view that binds to your new controller:

      ```handlebars
      {{#each MyApp.listController}}
        {{firstName}} {{lastName}}
      {{/each}}
      ```

      Although you are binding to the controller, the behavior of this controller
      is to pass through any methods or properties to the underlying array. This
      capability comes from `Ember.ArrayProxy`, which this class inherits from.

      Sometimes you want to display computed properties within the body of an
      `#each` helper that depend on the underlying items in `model`, but are not
      present on those items.   To do this, set `itemController` to the name of a
      controller (probably an `ObjectController`) that will wrap each individual item.

      For example:

      ```handlebars
        {{#each post in controller}}
          <li>{{post.title}} ({{post.titleLength}} characters)</li>
        {{/each}}
      ```

      ```javascript
      App.PostsController = Ember.ArrayController.extend({
        itemController: 'post'
      });

      App.PostController = Ember.ObjectController.extend({
        // the `title` property will be proxied to the underlying post.

        titleLength: function() {
          return this.get('title').length;
        }.property('title')
      });
      ```

      In some cases it is helpful to return a different `itemController` depending
      on the particular item.  Subclasses can do this by overriding
      `lookupItemController`.

      For example:

      ```javascript
      App.MyArrayController = Ember.ArrayController.extend({
        lookupItemController: function( object ) {
          if (object.get('isSpecial')) {
            return "special"; // use App.SpecialController
          } else {
            return "regular"; // use App.RegularController
          }
        }
      });
      ```

      The itemController instances will have a `parentController` property set to
      the `ArrayController` instance.

      @class ArrayController
      @namespace Ember
      @extends Ember.ArrayProxy
      @uses Ember.SortableMixin
      @uses Ember.ControllerMixin

    var ArrayController = ArrayProxy.extend(ControllerMixin, SortableMixin, {

        Return the name of the controller to wrap items, or `null` if items should
        be returned directly.  The default implementation simply returns the
        `itemController` property, but subclasses can override this method to return
        different controllers for different objects.

        For example:

        ```javascript
        App.MyArrayController = Ember.ArrayController.extend({
          lookupItemController: function( object ) {

            }
          }
        });

          }

        The `property` extension of Javascript's Function prototype is available
        when `Ember.EXTEND_PROTOTYPES` or `Ember.EXTEND_PROTOTYPES.Function` is
        `true`, which is the default.

        Computed properties allow you to treat a function like a property:

        ```javascript
        MyApp.President = Ember.Object.extend({
          firstName: '',
          lastName:  '',

          fullName: function() {
            return this.get('firstName') + ' ' + this.get('lastName');

            // Call this flag to mark the function as a property
          }.property()
        });

        var president = MyApp.President.create({
          firstName: "Barack",
          lastName: "Obama"
        });

        president.get('fullName');    // "Barack Obama"
        ```

        Treating a function like a property is useful because they can work with
        bindings, just like any other property.

        Many computed properties have dependencies on other properties. For
        example, in the above example, the `fullName` property depends on
        `firstName` and `lastName` to determine its value. You can tell Ember
        about these dependencies like this:

        ```javascript
        MyApp.President = Ember.Object.extend({
          firstName: '',
          lastName:  '',

          fullName: function() {
            return this.get('firstName') + ' ' + this.get('lastName');

            // Tell Ember.js that this computed property depends on firstName
            // and lastName
          }.property('firstName', 'lastName')
        });
        ```

        Make sure you list these dependencies so Ember knows when to update
        bindings that connect to a computed property. Changing a dependency
        will not immediately trigger an update of the computed property, but
        will instead clear the cache so that it is updated when the next `get`
        is called on the property.

        See [Ember.ComputedProperty](/api/classes/Ember.ComputedProperty.html), [Ember.computed](/api/#method_computed).

        @method property
        @for Function
      */

        var ret = computed(this);

        when `Ember.EXTEND_PROTOTYPES` or `Ember.EXTEND_PROTOTYPES.Function` is

        You can observe property changes simply by adding the `observes`
        call to the end of your method declarations in classes that you write.
        For example:

        ```javascript

      The `Ember.ActionHandler` mixin implements support for moving an `actions`
      property to an `_actions` property at extend time, and adding `_actions`
      to the object's mergedProperties list.

      `Ember.ActionHandler` is available on some familiar classes including
      `Ember.Route`, `Ember.View`, `Ember.Component`, and controllers such as
      `Ember.Controller` and `Ember.ObjectController`.
      (Internally the mixin is used by `Ember.CoreView`, `Ember.ControllerMixin`,
      and `Ember.Route` and available to the above classes through
      inheritance.)

      @class ActionHandler
      @namespace Ember
    */
    var ActionHandler = Mixin.create({
      mergedProperties: ['_actions'],

      /**
        The collection of functions, keyed by name, available on this
        `ActionHandler` as action targets.

        These functions will be invoked when a matching `{{action}}` is triggered
        from within a template and the application's current route is this route.

        Actions can also be invoked from other parts of your application
        via `ActionHandler#send`.

        The `actions` hash will inherit action handlers from
        the `actions` hash defined on extended parent classes
        or mixins rather than just replace the entire hash, e.g.:

        ```js
        App.CanDisplayBanner = Ember.Mixin.create({
          actions: {
            displayBanner: function(msg) {
              // ...
            }
          }
        });

        App.WelcomeRoute = Ember.Route.extend(App.CanDisplayBanner, {
          actions: {
            playMusic: function() {
              // ...
            }
          }
        });

        // `WelcomeRoute`, when active, will be able to respond
        // to both actions, since the actions hash is merged rather
        // then replaced when extending mixins / parent classes.
        this.send('displayBanner');
        this.send('playMusic');
        ```

        Within a Controller, Route, View or Component's action handler,
        the value of the `this` context is the Controller, Route, View or
        Component object:

        ```js
        App.SongRoute = Ember.Route.extend({
          actions: {
            myAction: function() {
              this.controllerFor("song");
              this.transitionTo("other.route");
              ...
            }
          }
        });
        ```

        It is also possible to call `this._super()` from within an
        action handler if it overrides a handler defined on a parent
        class or mixin:

        Take for example the following routes:

        ```js
        App.DebugRoute = Ember.Mixin.create({
          actions: {
            debugRouteInformation: function() {
              console.debug("trololo");
            }
          }
        });

        App.AnnoyingDebugRoute = Ember.Route.extend(App.DebugRoute, {
          actions: {
            debugRouteInformation: function() {
              // also call the debugRouteInformation of mixed in App.DebugRoute
              this._super();

              // show additional annoyance
              window.alert(...);
            }
          }
        });
        ```

        ## Bubbling

        By default, an action will stop bubbling once a handler defined
        on the `actions` hash handles it. To continue bubbling the action,
        you must return `true` from the handler:

        ```js
        App.Router.map(function() {
          this.resource("album", function() {
            this.route("song");
          });
        });

        App.AlbumRoute = Ember.Route.extend({
          actions: {
            startPlaying: function() {
            }
          }
        });

        App.AlbumSongRoute = Ember.Route.extend({
          actions: {
            startPlaying: function() {
              // ...

              if (actionShouldAlsoBeTriggeredOnParentRoute) {
                return true;
              }
            }
          }
        });
        ```

        if (!props._actions) {

        bubble to the `target`. Bubbling happens when an `actionName` can

    /**
      This mixin implements Observer-friendly Array-like behavior. It is not a
      concrete implementation, but it can be used up by other classes that want
      to appear like arrays.

      For example, ArrayProxy and ArrayController are both concrete classes that can
      be instantiated to implement array-like behavior. Both of these classes use
      the Array Mixin by way of the MutableArray mixin, which allows observable
      changes to be made to the underlying array.

      Unlike `Ember.Enumerable,` this mixin defines methods specifically for
      collections that provide index-ordered access to their contents. When you
      are designing code that needs to accept any kind of Array-like object, you
      should use these methods instead of Array primitives because these will
      properly notify observers of changes to the array.

      Although these methods are efficient, they do add a layer of indirection to
      your application so it is a good idea to use them only when you need the
      flexibility of using both true JavaScript arrays and "virtual" arrays such
      as controllers and collections.

      You can use the methods defined in this module to access and modify array
      contents in a KVO-friendly way. You can also be notified whenever the
      membership of an array changes by using `.observes('myArray.[]')`.

      To support `Ember.Array` in your own class, you must override two
      primitives to use it: `replace()` and `objectAt()`.

      Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
      mixin. All `Ember.Array`-like objects are also enumerable.

      @class Array

        or is greater or equal than the array length, returns `undefined`.

        This is one of the primitives you must implement to support `Ember.Array`.
        If your object supports retrieving the value of an array item using `get()`
        (i.e. `myArray.get(0)`), then you do not need to implement this method
        yourself.

    /**
      This mixin defines the common interface implemented by enumerable objects
      in Ember. Most of these methods follow the standard Array iteration
      API defined up to JavaScript 1.8 (excluding language-specific features that
      cannot be emulated in older versions of JavaScript).

      This mixin is applied automatically to the Array class on page load, so you
      can use any of these methods on simple arrays. If Array already implements
      one of these methods, the mixin will not override them.

      ## Writing Your Own Enumerable

      To make your own custom class enumerable, you need two items:

      1. You must have a length property. This property should change whenever
         the number of items in your enumerable object changes. If you use this
         with an `Ember.Object` subclass, you should be sure to change the length
         property using `set().`

      2. You must implement `nextObject().` See documentation.

      Once you have these two methods implemented, apply the `Ember.Enumerable` mixin
      to your class and you will be able to enumerate the contents of your object
      like any other collection.

      ## Using Ember Enumeration with Other Libraries

      Many other libraries provide some kind of iterator or enumeration like
      facility. This is often where the most common API conflicts occur.
      Ember's API is designed to be as friendly as possible with other
      libraries by implementing only methods that mostly correspond to the
      JavaScript 1.8 API.

      @class Enumerable
      @namespace Ember
      @since Ember 0.9
    */
    var Enumerable = Mixin.create({

      /**
        Implement this method to make your class enumerable.

        This method will be call repeatedly during enumeration. The index value
        will always begin with 0 and increment monotonically. You don't have to
        rely on the index value to determine what object to return, but you should
        always check the value and start from the beginning when you see the
        requested index is 0.

        The `previousObject` is the object that was returned from the last call
        to `nextObject` for the current iteration. This is a useful way to
        manage iteration if you are tracing a linked list, for example.

        Finally the context parameter will always contain a hash you can use as
        a "scratchpad" to maintain any other state you need in order to iterate
        properly. The context object is reused and is not reset between
        iterations so make sure you setup the context with a fresh state whenever
        the index parameter is 0.

        Generally iterators will continue to call `nextObject` until the index
        reaches the your current length-1. If you run out of data before this
        time for some reason, you should simply return undefined.

        The default implementation of this method simply looks up the index.
        This works great on any Array-like objects.

        @method nextObject
        @param {Number} index the current index of the iteration
        @param {Object} previousObject the value returned by the last call to
          `nextObject`.

      The `Ember.Freezable` mixin implements some basic methods for marking an
      object as frozen. Once an object is frozen it should be read only. No changes
      may be made the internal state of the object.

      ## Enforcement

      To fully support freezing in your subclass, you must include this mixin and
      override any method that might alter any property on the object to instead
      raise an exception. You can check the state of an object by checking the
      `isFrozen` property.

      Although future versions of JavaScript may support language-level freezing
      object objects, that is not the case today. Even if an object is freezable,
      it is still technically possible to modify the object, even though it could
      break other parts of your application that do not expect a frozen object to
      change. It is, therefore, very important that you always respect the
      `isFrozen` property on all freezable objects.

      ## Example Usage

      The example below shows a simple object that implement the `Ember.Freezable`
      protocol.

      ```javascript
      Contact = Ember.Object.extend(Ember.Freezable, {
        firstName: null,
        lastName: null,

        // swaps the names
        swapNames: function() {
          if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
          var tmp = this.get('firstName');
          this.set('firstName', this.get('lastName'));
          this.set('lastName', tmp);
          return this;
        }

      });

      c = Contact.create({ firstName: "John", lastName: "Doe" });
      c.swapNames();  // returns c
      c.freeze();
      c.swapNames();  // EXCEPTION
      ```

      ## Copying

      Usually the `Ember.Freezable` protocol is implemented in cooperation with the
      `Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
      return a frozen object, if the object implements this method as well.

      ## Adding Objects

      To add an object to an enumerable, use the `addObject()` method. This
      method will only add the object to the enumerable if the object is not
      already present and is of a type supported by the enumerable.

      ```javascript
      set.addObject(contact);
      ```

      ## Removing Objects

      To remove an object from an enumerable, use the `removeObject()` method. This
      will only remove the object if it is present in the enumerable, otherwise
      this method has no effect.

      ```javascript

      ## Implementing In Your Own Code

      If you are implementing an object and want to support this API, just include
      this mixin in your class and implement the required methods. In your unit
      tests, be sure to apply the Ember.MutableEnumerableTests to your object.

    /**
      ## Overview

      This mixin provides properties and property observing functionality, core
      features of the Ember object model.

      Properties and observers allow one object to observe changes to a
      property on another object. This is one of the fundamental ways that
      models, controllers and views communicate with each other in an Ember
      application.

      Any object that has this mixin applied can be used in observer
      operations. That includes `Ember.Object` and most objects you will
      interact with as you write your Ember application.

      Note that you will not generally apply this mixin to classes yourself,
      but you will use the features provided by this module frequently, so it
      is important to understand how to use it.

      ## Using `get()` and `set()`

      Because of Ember's support for bindings and observers, you will always
      access properties using the get method, and set properties using the
      set method. This allows the observing objects to be notified and
      computed properties to be handled properly.

      More documentation about `get` and `set` are below.

      ## Observing Property Changes

      You typically observe property changes simply by adding the `observes`
      call to the end of your method declarations in classes that you write.
      For example:

      ```javascript
      Ember.Object.extend({
        valueObserver: function() {
          // Executes whenever the "value" property changes
        }.observes('value')
      });
      ```

      Although this is the most common way to add an observer, this capability
      is actually built into the `Ember.Object` class on top of two methods
      defined in this mixin: `addObserver` and `removeObserver`. You can use
      these two methods to add and remove observers yourself if you need to
      do so at runtime.

      To add an observer for a property, call:

      ```javascript
      object.addObserver('propertyKey', targetObject, targetAction)
      ```

      This will call the `targetAction` method on the `targetObject` whenever
      the value of the `propertyKey` changes.

      Note that if `propertyKey` is a computed property, the observer will be
      called when any of the property dependencies are changed, even if the
      resulting value of the computed property is unchanged. This is necessary
      because computed properties are not computed until `get` is called.

      @class Observable
      @namespace Ember
    */
    var Observable = Mixin.create({

      /**
        Retrieves the value of a property from the object.

        This method is usually similar to using `object[keyName]` or `object.keyName`,
        however it supports both computed properties and the unknownProperty
        handler.

        Because `get` unifies the syntax for accessing all these kinds
        of properties, it can make many refactorings easier, such as replacing a
        simple property with a computed property, or vice versa.

        ### Computed Properties

        Computed properties are methods defined with the `property` modifier
        declared at the end, such as:

        ```javascript
        fullName: function() {
          return this.get('firstName') + ' ' + this.get('lastName');
        }.property('firstName', 'lastName')
        ```

        When you call `get` on a computed property, the function will be
        called and the return value will be returned instead of the function
        itself.

        ### Unknown Properties

        Likewise, if you try to call `get` on a property whose value is
        `undefined`, the `unknownProperty()` method will be called on the object.
        If this method returns any value other than `undefined`, it will be returned
        instead. This allows you to implement "virtual" properties that are
        not defined upfront.

        @method get
        @param {String} keyName The property to retrieve
        @return {Object} The property value or undefined.
      */
      get: function(keyName) {
        return get(this, keyName);
      },

      /**
        To get multiple properties at once, call `getProperties`
        with a list of strings or an array:

        ```javascript
        record.getProperties('firstName', 'lastName', 'zipCode');  // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
        ```

        is equivalent to:

        ```javascript
        record.getProperties(['firstName', 'lastName', 'zipCode']);  // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
        ```

        @method getProperties
        @param {String...|Array} list of keys to get
        @return {Hash}
      */
      getProperties: function() {
        return apply(null, getProperties, [this].concat(slice.call(arguments)));
      },

      /**
        Sets the provided key or path to the value.

        This method is generally very similar to calling `object[key] = value` or
        `object.key = value`, except that it provides support for computed
        properties, the `setUnknownProperty()` method and property observers.

        ### Computed Properties

        If you try to set a value on a key that has a computed property handler
        defined (see the `get()` method for an example), then `set()` will call
        that method, passing both the value and key instead of simply changing
        the value itself. This is useful for those times when you need to
        implement a property that is composed of one or more member
        properties.

        ### Unknown Properties

        If you try to set a value on a key that is undefined in the target
        object, then the `setUnknownProperty()` handler will be called instead. This
        gives you an opportunity to implement complex "virtual" properties that
        are not predefined on the object. If `setUnknownProperty()` returns
        undefined, then `set()` will simply set the value on the object.

        ### Property Observers

        In addition to changing the property, `set()` will also register a property
        change with the object. Unless you have placed this call inside of a
        `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
        (i.e. observer methods declared on the same object), will be called
        immediately. Any "remote" observers (i.e. observer methods declared on
        another object) will be placed in a queue and called at a later time in a
        coalesced manner.

        ### Chaining

        In addition to property changes, `set()` returns the value of the object
        itself so you can do chaining like this:

        ```javascript
        record.set('firstName', 'Charles').set('lastName', 'Jolley');
        ```

        @method set
        @param {String} keyName The property to set
        @param {Object} value The value to set or `null`.
        @return {Ember.Observable}
      */
      set: function(keyName, value) {
        set(this, keyName, value);
        return this;
      },


      /**
        Sets a list of properties at once. These properties are set inside
        a single `beginPropertyChanges` and `endPropertyChanges` batch, so
        observers will be buffered.

        ```javascript
        record.setProperties({ firstName: 'Charles', lastName: 'Jolley' });
        ```

        @method setProperties
        @param {Hash} hash the hash of keys and values to set
        @return {Ember.Observable}
      */
      setProperties: function(hash) {
        return setProperties(this, hash);
      },

      /**

        will not be sent until the changes are finished. If you plan to make a

        method at the beginning of the changes to begin deferring change
        notifications. When you are done making changes, call
        `endPropertyChanges()` to deliver the deferred change notifications and end
        deferring.

        @return {Ember.Observable}

      beginPropertyChanges: function() {

        Adds an observer on a property.

        This is the core method used to register an observer for a property.

        Once you call this method, any time the key's value is set, your observer
        will be notified. Note that the observers are triggered any time the
        value is set, regardless of whether it has actually changed. Your
        observer should be prepared to handle that.

        You can also pass an optional context parameter to this method. The
        context will be passed to your observer method whenever it is triggered.
        Note that if you add the same target/method pair on a key multiple times
        with different context parameters, your observer will only be called once
        with the last context you passed.

        ### Observer Methods

        Observer methods you pass should generally have the following signature if
        you do not pass a `context` parameter:

        ```javascript
        fooDidChange: function(sender, key, value, rev) { };
        ```

        The sender is the object that changed. The key is the property that
        changes. The value property is currently reserved and unused. The rev
        is the last property revision of the object when it changed, which you can
        use to detect if the key value has really changed or not.

        If you pass a `context` parameter, the context will be passed before the
        revision like so:

        ```javascript
        fooDidChange: function(sender, key, value, context, rev) { };
        ```

        Usually you will not need the value, context or revision parameters at
        the end. In this case, it is common to write observer methods that take
        only a sender and key value as parameters or, if you aren't interested in
        any of these values, to write an observer that has no parameters at all.

        @method addObserver
        @param {String} key The key to observer
        @param {Object} target The target object to invoke
        @param {String|Function} method The method to invoke.

      the controller has bindable attributes which
      track the promises life cycle

      ```javascript
      controller.get('isPending')   //=> true
      controller.get('isSettled')  //=> false
      controller.get('isRejected')  //=> false
      controller.get('isFulfilled') //=> false
      ```

      When the the $.getJSON completes, and the promise is fulfilled
      with json, the life cycle attributes will update accordingly.

      ```javascript
      controller.get('isPending')   //=> false
      controller.get('isSettled')   //=> true
      controller.get('isRejected')  //=> false
      controller.get('isFulfilled') //=> true
      ```

      As the controller is an ObjectController, and the json now its content,
      all the json properties will be available directly from the controller.

      ```javascript
      // Assuming the following json:
      {
        firstName: 'Stefan',
        lastName: 'Penner'
      }

      // both properties will accessible on the controller
      controller.get('firstName') //=> 'Stefan'
      controller.get('lastName')  //=> 'Penner'
      ```

      If the controller is backing a template, the attributes are
      bindable from within that template

      ```handlebars

      `Ember.SortableMixin` provides a standard interface for array proxies
      to specify a sort order and maintain this sorting when objects are added,
      removed, or updated without changing the implicit order of their underlying
      modelarray:

      ```javascript
      songs = [
        {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'},
        {trackNumber: 2, title: 'Back in the U.S.S.R.'},
        {trackNumber: 3, title: 'Glass Onion'},
      ];

      songsController = Ember.ArrayController.create({
        model: songs,
        sortProperties: ['trackNumber'],
        sortAscending: true
      });

      songsController.get('firstObject');  // {trackNumber: 2, title: 'Back in the U.S.S.R.'}

      songsController.addObject({trackNumber: 1, title: 'Dear Prudence'});
      songsController.get('firstObject');  // {trackNumber: 1, title: 'Dear Prudence'}
      ```

      If you add or remove the properties to sort by or change the sort direction the model
      sort order will be automatically updated.

      ```javascript
      songsController.set('sortProperties', ['title']);
      songsController.get('firstObject'); // {trackNumber: 2, title: 'Back in the U.S.S.R.'}

      songsController.toggleProperty('sortAscending');
      songsController.get('firstObject'); // {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'}
      ```

      SortableMixin works by sorting the arrangedContent array, which is the array that
      arrayProxy displays. Due to the fact that the underlying 'content' array is not changed, that
      array will not display the sorted list:

       ```javascript
      songsController.get('content').get('firstObject'); // Returns the unsorted original content
      songsController.get('firstObject'); // Returns the sorted content.
      ```

      Although the sorted content can also be accessed through the arrangedContent property,
      it is preferable to use the proxied class and not the arrangedContent array directly.

        target: Ember.computed.alias('controller'),
        action: 'save',

      The `target`, `action`, and `actionContext` can be provided as properties of

        }
      });

      The `actionContext` defaults to the object you are mixing `TargetActionSupport` into.
      But `target` and `action` must be specified either as properties or with the argument
      to `triggerAction`, or a combination:

      ```javascript
      App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
        target: Ember.computed.alias('controller'),
        click: function() {

        }
      });
      ```

      An ArrayProxy wraps any other object that implements `Ember.Array` and/or
      `Ember.MutableArray,` forwarding all requests. This makes it very useful for
      a number of binding use cases or other cases where being able to swap
      out the underlying array is useful.

      A simple example of usage:

      ```javascript
      var pets = ['dog', 'cat', 'fish'];
      var ap = Ember.ArrayProxy.create({ content: Ember.A(pets) });

      ap.get('firstObject');                        // 'dog'

      ap.get('firstObject');                        // 'amoeba'
      ```

      This class can also be useful as a layer to transform the contents of
      an array, as they are accessed. This can be done by overriding
      `objectAtContent`:

      ```javascript
      var pets = ['dog', 'cat', 'fish'];
      var ap = Ember.ArrayProxy.create({
          content: Ember.A(pets),

              return this.get('content').objectAt(idx).toUpperCase();
          }
      });

      ap.get('firstObject'); // . 'DOG'

        NOTE: If you do override `init` for a framework class like `Ember.View` or
        `Ember.ArrayController`, be sure to call `this._super()` in your
        `init` declaration! If you don't, Ember may not have an opportunity to
        do important setup work, and you'll see strange behavior in your
        application.

        @method init
      */
      init: function() {},

      /**
        Defines the properties that will be concatenated from the superclass
        (instead of overridden).

        By default, when you extend an Ember class a property defined in
        the subclass overrides a property with the same name that is defined
        in the superclass. However, there are some cases where it is preferable
        to build up a property's value by combining the superclass' property
        value with the subclass' value. An example of this in use within Ember
        is the `classNames` property of `Ember.View`.

        Here is some sample code showing the difference between a concatenated
        property and a normal one:

        ```javascript
        App.BarView = Ember.View.extend({
          someNonConcatenatedProperty: ['bar'],
          classNames: ['bar']
        });

        App.FooBarView = App.BarView.extend({
          someNonConcatenatedProperty: ['foo'],
          classNames: ['foo'],
        });

        var fooBarView = App.FooBarView.create();
        fooBarView.get('someNonConcatenatedProperty'); // ['foo']
        fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
        ```

        This behavior extends to object creation as well. Continuing the
        above example:

        ```javascript
        var view = App.FooBarView.create({
          someNonConcatenatedProperty: ['baz'],
          classNames: ['baz']
        })
        view.get('someNonConcatenatedProperty'); // ['baz']
        view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
        ```
        Adding a single property that is not an array will just add it in the array:

        ```javascript
        var view = App.FooBarView.create({
          classNames: 'baz'
        })
        view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
        ```

        Using the `concatenatedProperties` property, we can tell to Ember that mix
        the content of the properties.

        In `Ember.View` the `classNameBindings` and `attributeBindings` properties
        are also concatenated, in addition to `classNames`.

        This feature is available for you to use throughout the Ember object model,
        although typical app developers are likely to use it infrequently. Since
        it changes expectations about behavior of properties, you should properly
        document its usage in each individual concatenated property (to not
        mislead your users to think they can override the property in a subclass).

        person = App.Person.create()
        person.toString() //=> "<App.Person:ember1024>"
        ```

        If the object's class is not defined on an Ember namespace, it will
        indicate it is a subclass of the registered superclass:

        This defines a new subclass of Ember.Object: `App.Person`. It contains one method: `say()`.

        You can also create a subclass from any existing class by calling its `extend()`  method. For example, you might want to create a subclass of Ember's built-in `Ember.View` class:

        ```javascript
        App.PersonView = Ember.View.extend({
          tagName: 'li',
          classNameBindings: ['isAdministrator']
        });
        ```

        When defining a subclass, you can override methods but still access the implementation of your parent class by calling the special `_super()` method:

        ```javascript
        App.Person = Ember.Object.extend({
          say: function(thing) {
            var name = this.get('name');
            alert(name + ' says: ' + thing);
          }
        });

        App.Soldier = App.Person.extend({
          say: function(thing) {
            this._super(thing + ", sir!");
          },
          march: function(numberOfHours) {
            alert(this.get('name') + ' marches for ' + numberOfHours + ' hours.')
          }
        });

        var yehuda = App.Soldier.create({
          name: "Yehuda Katz"
        });

        yehuda.say("Yes");  // alerts "Yehuda Katz says: Yes, sir!"
        ```

        The `create()` on line #17 creates an *instance* of the `App.Soldier` class. The `extend()` on line #8 creates a *subclass* of `App.Person`. Any instance of the `App.Person` class will *not* have the `march()` method.

        You can also pass `Mixin` classes to add additional properties to the subclass.

        ```javascript
        App.Person = Ember.Object.extend({
          say: function(thing) {
            alert(this.get('name') + ' says: ' + thing);
          }
        });

        App.SingingMixin = Mixin.create({
          sing: function(thing){
            alert(this.get('name') + ' sings: la la la ' + thing);
          }
        });

        App.BroadwayStar = App.Person.extend(App.SingingMixin, {
          dance: function() {
            alert(this.get('name') + ' dances: tap tap tap tap ');
          }
        });
        ```

        The `App.BroadwayStar` class contains three methods: `say()`, `sing()`, and `dance()`.

        @method extend
        @static

        @param {Mixin} [mixins]* One or more Mixin classes

        Class.PrototypeMixin = Mixin.create(this.PrototypeMixin);

        Class.ClassMixin.ownerConstructor = Class;
        Class.PrototypeMixin.ownerConstructor = Class;

        reopen.apply(Class.PrototypeMixin, arguments);

          helloWorld: function() {
            alert("Hi, my name is " + this.get('name'));
          }
        });

          name: 'Tom Dale'
        });

        tom.helloWorld(); // alerts "Hi, my name is Tom Dale".
        ```

        `create` will call the `init` function if defined during
        `Ember.AnyObject.extend`

        If no arguments are passed to `create`, it will not set values to the new
        instance during initialization:

        ```javascript
        var noName = App.Person.create();
        noName.helloWorld(); // alerts undefined
        ```

        NOTE: For performance reasons, you cannot declare methods or computed
        properties during `create`. You should instead declare methods and computed
        properties when using `extend` or use the `createWithMixins` shorthand.

        @method create

        MyObject.canBuild; // false

        In other words, this creates static properties and functions for the class. These are only available on the class
        and not on any instance of that class.

        ```javascript
        App.Person = Ember.Object.extend({
          name : "",
          sayHello : function(){
            alert("Hello. My name is " + this.get('name'));
          }
        });

        App.Person.reopenClass({
          species : "Homo sapiens",
          createPerson: function(newPersonsName){
            return App.Person.create({
              name:newPersonsName
            });

          name : "Tom Dale"
        });
        var yehuda = App.Person.createPerson("Yehuda Katz");

        tom.sayHello(); // "Hello. My name is Tom Dale"
        yehuda.sayHello(); // "Hello. My name is Yehuda Katz"
        alert(App.Person.species); // "Homo sapiens"
        ```

        Note that `species` and `createPerson` are *not* valid on the `tom` and `yehuda`
        variables. They are only valid on `App.Person`.

        In some cases, you may want to annotate computed properties with additional

        example, computed property functions may close over variables that are then
        no longer available for introspection.

        You can pass a hash of these values to a computed property like this:

        ```javascript
        person: function() {

        Once you've done this, you can retrieve the values saved to the computed
        property from your class like this:

        ```javascript
        MyClass.metaForProperty('person');
        ```

        This will return the original hash that was passed to `meta()`.

    /**
      An unordered collection of objects.

      A Set works a bit like an array except that its items are not ordered. You
      can create a set to efficiently test for membership for an object. You can
      also iterate through a set just like an array, even accessing objects by
      index, however there is no guarantee as to their order.

      All Sets are observable via the Enumerable Observer API - which works
      on any enumerable object including both Sets and Arrays.

      ## Creating a Set

      You can create a set like you would most objects using
      `new Ember.Set()`. Most new sets you create will be empty, but you can
      also initialize the set with some content by passing an array or other
      enumerable of objects to the constructor.

      Finally, you can pass in an existing set and the set will be copied. You
      can also create a copy of a set by calling `Ember.Set#copy()`.

      ```javascript
      // creates a new empty set
      var foundNames = new Ember.Set();

      // creates a set with four names in it.
      var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P

      // creates a copy of the names set.
      var namesCopy = new Ember.Set(names);

      // same as above.
      var anotherNamesCopy = names.copy();
      ```

      ## Adding/Removing Objects

      You generally add or remove objects from a set using `add()` or
      `remove()`. You can add any type of object including primitives such as
      numbers, strings, and booleans.

      Unlike arrays, objects can only exist one time in a set. If you call `add()`
      on a set with the same object multiple times, the object will only be added
      once. Likewise, calling `remove()` with the same object multiple times will
      remove the object the first time and have no effect on future calls until
      you add the object to the set again.

      NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
      so will be ignored.

      In addition to add/remove you can also call `push()`/`pop()`. Push behaves
      just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
      object, remove it and return it. This is a good way to use a set as a job
      queue when you don't care which order the jobs are executed in.

      ## Testing for an Object

      To test for an object's presence in a set you simply call
      `Ember.Set#contains()`.

      ## Observing changes

      When using `Ember.Set`, you can observe the `"[]"` property to be
      alerted whenever the content changes. You can also add an enumerable
      observer to the set to be notified of specific objects that are added and
      removed from the set. See [Ember.Enumerable](/api/classes/Ember.Enumerable.html)
      for more information on enumerables.

      This is often unhelpful. If you are filtering sets of objects, for instance,
      it is very inefficient to re-filter all of the items each time the set
      changes. It would be better if you could just adjust the filtered set based
      on what was changed on the original set. The same issue applies to merging
      sets, as well.

      ## Other Methods

      `Ember.Set` primary implements other mixin APIs. For a complete reference
      on the methods you will use with `Ember.Set`, please consult these mixins.
      The most useful ones will be `Ember.Enumerable` and
      `Ember.MutableEnumerable` which implement most of the common iterator
      methods you are used to on Array.

      Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
      APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
      modified. The benefit of this is that when you call `frozenCopy()` on it,
      Ember will avoid making copies of the set. This allows you to write
      code that can know with certainty when the underlying set data will or
      will not be modified.

    `Ember.ViewTargetActionSupport` is a mixin that can be included in a
    view class to add a `triggerAction` method with semantics similar to
    the Handlebars `{{action}}` helper. It provides intelligent defaults
    for the action's target: the view's controller; and the context that is
    sent with the action: the view's context.

    Note: In normal Ember usage, the `{{action}}` helper is usually the best
    choice. This mixin is most often useful when you are doing more complex
    event handling in custom View subclasses.

    For example:

    ```javascript
    App.SaveButtonView = Ember.View.extend(Ember.ViewTargetActionSupport, {
      action: 'save',
      click: function() {
        this.triggerAction(); // Sends the `save` action, along with the current context
                              // to the current controller
      }
    });
    ```

    The `action` can be provided as properties of an optional object argument
    to `triggerAction` as well.

    ```javascript
    App.SaveButtonView = Ember.View.extend(Ember.ViewTargetActionSupport, {
      click: function() {
        this.triggerAction({
          action: 'save'
        }); // Sends the `save` action, along with the current context
            // to the current controller
      }

    /**
      `Ember.CollectionView` is an `Ember.View` descendent responsible for managing
      a collection (an array or array-like object) by maintaining a child view object
      and associated DOM representation for each item in the array and ensuring
      that child views and their associated rendered HTML are updated when items in
      the array are added, removed, or replaced.

      ## Setting content

      The managed collection of objects is referenced as the `Ember.CollectionView`
      instance's `content` property.

      ```javascript
      someItemsView = Ember.CollectionView.create({
        content: ['A', 'B','C']
      })
      ```

      The view for each item in the collection will have its `content` property set
      to the item.

      ## Specifying itemViewClass

      By default the view class for each item in the managed collection will be an
      instance of `Ember.View`. You can supply a different class by setting the
      `CollectionView`'s `itemViewClass` property.

      Given an empty `<body>` and the following code:

      ```javascript
      someItemsView = Ember.CollectionView.create({
        classNames: ['a-collection'],
        content: ['A','B','C'],
        itemViewClass: Ember.View.extend({
          template: Ember.Handlebars.compile("the letter: {{view.content}}")
        })
      });

      someItemsView.appendTo('body');
      ```

      Will result in the following HTML structure

      ```html
      <div class="ember-view a-collection">
        <div class="ember-view">the letter: A</div>
        <div class="ember-view">the letter: B</div>
        <div class="ember-view">the letter: C</div>
      </div>
      ```

      ## Automatic matching of parent/child tagNames

      Setting the `tagName` property of a `CollectionView` to any of
      "ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
      in the item views receiving an appropriately matched `tagName` property.

      Given an empty `<body>` and the following code:

      ```javascript
      anUnorderedListView = Ember.CollectionView.create({
        tagName: 'ul',
        content: ['A','B','C'],
        itemViewClass: Ember.View.extend({
          template: Ember.Handlebars.compile("the letter: {{view.content}}")
        })
      });

      anUnorderedListView.appendTo('body');
      ```

      Will result in the following HTML structure

      ```html
      <ul class="ember-view a-collection">
        <li class="ember-view">the letter: A</li>
        <li class="ember-view">the letter: B</li>
        <li class="ember-view">the letter: C</li>
      </ul>
      ```

      Additional `tagName` pairs can be provided by adding to
      `Ember.CollectionView.CONTAINER_MAP `

      ```javascript
      Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
      ```

      ## Programmatic creation of child views

      For cases where additional customization beyond the use of a single
      `itemViewClass` or `tagName` matching is required CollectionView's
      `createChildView` method can be overidden:

      ```javascript
      CustomCollectionView = Ember.CollectionView.extend({
        createChildView: function(viewClass, attrs) {
          if (attrs.content.kind == 'album') {
            viewClass = App.AlbumView;
          } else {
            viewClass = App.SongView;
          }
          return this._super(viewClass, attrs);
        }
      });
      ```

      ## Empty View

      You can provide an `Ember.View` subclass to the `Ember.CollectionView`
      instance as its `emptyView` property. If the `content` property of a
      `CollectionView` is set to `null` or an empty array, an instance of this view
      will be the `CollectionView`s only child.

      ```javascript
      aListWithNothing = Ember.CollectionView.create({
        classNames: ['nothing']
        content: null,
        emptyView: Ember.View.extend({
          template: Ember.Handlebars.compile("The collection is empty")
        })
      });

      aListWithNothing.appendTo('body');
      ```

      Will result in the following HTML structure

      ```html
      <div class="ember-view nothing">
        <div class="ember-view">
          The collection is empty
        </div>
      </div>
      ```

      ## Adding and Removing items

      The `childViews` property of a `CollectionView` should not be directly
      manipulated. Instead, add, remove, replace items from its `content` property.
      This will trigger appropriate changes to its rendered HTML.

      An `Ember.Component` is a view that is completely
      isolated. Property access in its templates go
      to the view object and actions are targeted at
      the view object. There is no access to the
      surrounding context or outer controller; all
      contextual information must be passed in.

      The easiest way to create an `Ember.Component` is via
      a template. If you name a template
      `components/my-foo`, you will be able to use
      `{{my-foo}}` in other templates, which will make
      an instance of the isolated component.

      ```handlebars
      {{app-profile person=currentUser}}
      ```

      ```handlebars
      <!-- app-profile template -->
      <h1>{{person.title}}</h1>
      <img {{bind-attr src=person.avatar}}>
      <p class='signature'>{{person.signature}}</p>
      ```

      You can use `yield` inside a template to
      include the **contents** of any block attached to
      the component. The block will be executed in the
      context of the surrounding context or outer controller:

      ```handlebars
      {{#app-profile person=currentUser}}
        <p>Admin mode</p>
        {{! Executed in the controller's context. }}
      {{/app-profile}}
      ```

      ```handlebars
      <!-- app-profile template -->
      <h1>{{person.title}}</h1>
      {{! Executed in the components context. }}
      {{yield}} {{! block contents }}
      ```

      If you want to customize the component, in order to
      handle events or actions, you implement a subclass
      of `Ember.Component` named after the name of the
      component. Note that `Component` needs to be appended to the name of
      your subclass like `AppProfileComponent`.

      For example, you could implement the action
      `hello` for the `app-profile` component:

      ```javascript
      App.AppProfileComponent = Ember.Component.extend({
        actions: {
          hello: function(name) {
            console.log("Hello", name);
          }
        }
      });
      ```

      And then use it in the component's template:

      ```handlebars
      <!-- app-profile template -->

      <h1>{{person.title}}</h1>
      {{yield}} <!-- block contents -->

      <button {{action 'hello' person.name}}>
        Say Hello to {{person.name}}
      </button>
      ```

      Components must have a `-` in their name to avoid
      conflicts with built-in controls that wrap HTML
      elements. This is consistent with the same
      requirement in web components.

      @class Component
      @namespace Ember

      /**
        Triggers a named action on the controller context where the component is used if
        this controller has registered for notifications of the action.

        For example a component for playing or pausing music may translate click events
        into action notifications of "play" or "stop" depending on some internal state
        of the component:


        ```javascript
        App.PlayButtonComponent = Ember.Component.extend({
          click: function(){
            if (this.get('isPlaying')) {
              this.sendAction('play');
            } else {
              this.sendAction('stop');
            }
          }
        });
        ```

        When used inside a template these component actions are configured to
        trigger actions in the outer application context:

        ```handlebars
        {{! application.hbs }}
        {{play-button play="musicStarted" stop="musicStopped"}}
        ```

        When the component receives a browser `click` event it translate this
        interaction into application-specific semantics ("play" or "stop") and
        triggers the specified action name on the controller for the template
        where the component is used:


        ```javascript
        App.ApplicationController = Ember.Controller.extend({
          actions: {
            musicStarted: function(){
              // called when the play button is clicked
              // and the music started playing
            },
            musicStopped: function(){
              // called when the play button is clicked
              // and the music stopped playing
            }
          }
        });
        ```

        If no action name is passed to `sendAction` a default name of "action"
        is assumed.

        ```javascript
        App.NextButtonComponent = Ember.Component.extend({
          click: function(){
            this.sendAction();
          }
        });
        ```

        ```handlebars
        {{! application.hbs }}
        {{next-button action="playNextSongInAlbum"}}
        ```

        ```javascript
        App.ApplicationController = Ember.Controller.extend({
          actions: {
            playNextSongInAlbum: function(){
              ...
            }
          }
        });
        ```

        @method sendAction
        @param [action] {String} the action to trigger

      A `ContainerView` is an `Ember.View` subclass that implements `Ember.MutableArray`
      allowing programmatic management of its child views.

      ## Setting Initial Child Views

      The initial array of child views can be set in one of two ways. You can
      provide a `childViews` property at creation time that contains instance of
      `Ember.View`:

      ```javascript
      aContainer = Ember.ContainerView.create({
        childViews: [Ember.View.create(), Ember.View.create()]
      });
      ```

      You can also provide a list of property names whose values are instances of
      `Ember.View`:

      ```javascript
      aContainer = Ember.ContainerView.create({
        childViews: ['aView', 'bView', 'cView'],
        aView: Ember.View.create(),
        bView: Ember.View.create(),
        cView: Ember.View.create()
      });
      ```

      The two strategies can be combined:

      ```javascript
      aContainer = Ember.ContainerView.create({
        childViews: ['aView', Ember.View.create()],
        aView: Ember.View.create()
      });
      ```

      Each child view's rendering will be inserted into the container's rendered
      HTML in the same order as its position in the `childViews` property.

      ## Adding and Removing Child Views

      The container view implements `Ember.MutableArray` allowing programmatic management of its child views.

      To remove a view, pass that view into a `removeObject` call on the container view.

      Given an empty `<body>` the following code

      ```javascript
      aContainer = Ember.ContainerView.create({
        classNames: ['the-container'],
        childViews: ['aView', 'bView'],
        aView: Ember.View.create({
          template: Ember.Handlebars.compile("A")
        }),
        bView: Ember.View.create({
          template: Ember.Handlebars.compile("B")
        })
      });

      aContainer.appendTo('body');
      ```

      Results in the HTML

      ```html
      <div class="ember-view the-container">
        <div class="ember-view">A</div>
        <div class="ember-view">B</div>
      </div>
      ```

      Removing a view

      ```javascript
      aContainer.toArray();  // [aContainer.aView, aContainer.bView]
      aContainer.removeObject(aContainer.get('bView'));
      aContainer.toArray();  // [aContainer.aView]
      ```

      Will result in the following HTML

      ```html
      <div class="ember-view the-container">
        <div class="ember-view">A</div>
      </div>
      ```

      Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
      container view.

      Given an empty `<body>` the following code

      ```javascript
      aContainer = Ember.ContainerView.create({
        classNames: ['the-container'],
        childViews: ['aView', 'bView'],
        aView: Ember.View.create({
          template: Ember.Handlebars.compile("A")
        }),
        bView: Ember.View.create({
          template: Ember.Handlebars.compile("B")
        })
      });

      aContainer.appendTo('body');
      ```

      Results in the HTML

      ```html
      <div class="ember-view the-container">
        <div class="ember-view">A</div>
        <div class="ember-view">B</div>
      </div>
      ```

      Adding a view

      ```javascript
      AnotherViewClass = Ember.View.extend({
        template: Ember.Handlebars.compile("Another view")
      });

      aContainer.toArray();  // [aContainer.aView, aContainer.bView]
      aContainer.pushObject(AnotherViewClass.create());
      aContainer.toArray(); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
      ```

      Will result in the following HTML

      ```html
      <div class="ember-view the-container">
        <div class="ember-view">A</div>
        <div class="ember-view">B</div>
        <div class="ember-view">Another view</div>
      </div>
      ```

      ## Templates and Layout

      A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or
      `defaultLayout` property on a container view will not result in the template
      or layout being rendered. The HTML contents of a `Ember.ContainerView`'s DOM
      representation will only be the rendered HTML of its child views.

      @class ContainerView
      @namespace Ember
      @extends Ember.View

    /**
      `Ember.View` is the class in Ember responsible for encapsulating templates of
      HTML content, combining templates with data to render as sections of a page's
      DOM, and registering and responding to user-initiated events.

      ## HTML Tag

      The default HTML tag name used for a view's DOM representation is `div`. This
      can be customized by setting the `tagName` property. The following view
      class:

      ```javascript
      ParagraphView = Ember.View.extend({
        tagName: 'em'
      });
      ```

      Would result in instances with the following HTML:

      ```html
      <em id="ember1" class="ember-view"></em>
      ```

      ## HTML `class` Attribute

      The HTML `class` attribute of a view's tag can be set by providing a
      `classNames` property that is set to an array of strings:

      ```javascript
      MyView = Ember.View.extend({
        classNames: ['my-class', 'my-other-class']
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view my-class my-other-class"></div>
      ```

      `class` attribute values can also be set by providing a `classNameBindings`
      property set to an array of properties names for the view. The return value
      of these properties will be added as part of the value for the view's `class`
      attribute. These properties can be computed properties:

      ```javascript
      MyView = Ember.View.extend({
        classNameBindings: ['propertyA', 'propertyB'],
        propertyA: 'from-a',
        propertyB: function() {
          if (someLogic) { return 'from-b'; }
        }.property()
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view from-a from-b"></div>
      ```

      If the value of a class name binding returns a boolean the property name
      itself will be used as the class name if the property is true. The class name
      will not be added if the value is `false` or `undefined`.

      ```javascript
      MyView = Ember.View.extend({
        classNameBindings: ['hovered'],
        hovered: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view hovered"></div>
      ```

      When using boolean class name bindings you can supply a string value other
      than the property name for use as the `class` HTML attribute by appending the
      preferred value after a ":" character when defining the binding:

      ```javascript
      MyView = Ember.View.extend({
        classNameBindings: ['awesome:so-very-cool'],
        awesome: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view so-very-cool"></div>
      ```

      Boolean value class name bindings whose property names are in a
      camelCase-style format will be converted to a dasherized format:

      ```javascript
      MyView = Ember.View.extend({
        classNameBindings: ['isUrgent'],
        isUrgent: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view is-urgent"></div>
      ```

      Class name bindings can also refer to object values that are found by
      traversing a path relative to the view itself:

      ```javascript
      MyView = Ember.View.extend({
        classNameBindings: ['messages.empty']
        messages: Ember.Object.create({
          empty: true
        })
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view empty"></div>
      ```

      If you want to add a class name for a property which evaluates to true and
      and a different class name if it evaluates to false, you can pass a binding
      like this:

      ```javascript
      // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
      Ember.View.extend({
        classNameBindings: ['isEnabled:enabled:disabled']
        isEnabled: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view enabled"></div>
      ```

      When isEnabled is `false`, the resulting HTML reprensentation looks like
      this:

      ```html
      <div id="ember1" class="ember-view disabled"></div>
      ```

      This syntax offers the convenience to add a class if a property is `false`:

      ```javascript
      // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
      Ember.View.extend({
        classNameBindings: ['isEnabled::disabled']
        isEnabled: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view"></div>
      ```

      When the `isEnabled` property on the view is set to `false`, it will result
      in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view disabled"></div>
      ```

      Updates to the the value of a class name binding will result in automatic
      update of the  HTML `class` attribute in the view's rendered HTML
      representation. If the value becomes `false` or `undefined` the class name
      will be removed.

      Both `classNames` and `classNameBindings` are concatenated properties. See
      [Ember.Object](/api/classes/Ember.Object.html) documentation for more
      information about concatenated properties.

      ## HTML Attributes

      The HTML attribute section of a view's tag can be set by providing an
      `attributeBindings` property set to an array of property names on the view.
      The return value of these properties will be used as the value of the view's
      HTML associated attribute:

      ```javascript
      AnchorView = Ember.View.extend({
        tagName: 'a',
        attributeBindings: ['href'],
        href: 'http://google.com'
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <a id="ember1" class="ember-view" href="http://google.com"></a>
      ```

      One property can be mapped on to another by placing a ":" between
      the source property and the destination property:

      ```javascript
      AnchorView = Ember.View.extend({
        tagName: 'a',
        attributeBindings: ['url:href'],
        url: 'http://google.com'
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <a id="ember1" class="ember-view" href="http://google.com"></a>
      ```

      If the return value of an `attributeBindings` monitored property is a boolean
      the property will follow HTML's pattern of repeating the attribute's name as
      its value:

      ```javascript
      MyTextInput = Ember.View.extend({
        tagName: 'input',
        attributeBindings: ['disabled'],
        disabled: true
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <input id="ember1" class="ember-view" disabled="disabled" />
      ```

      `attributeBindings` can refer to computed properties:

      ```javascript
      MyTextInput = Ember.View.extend({
        tagName: 'input',
        attributeBindings: ['disabled'],
        disabled: function() {
          if (someLogic) {
            return true;
          } else {
            return false;
          }
        }.property()
      });
      ```

      Updates to the the property of an attribute binding will result in automatic
      update of the  HTML attribute in the view's rendered HTML representation.

      `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html)
      documentation for more information about concatenated properties.

      ## Templates

      The HTML contents of a view's rendered representation are determined by its
      template. Templates can be any function that accepts an optional context
      parameter and returns a string of HTML that will be inserted within the
      view's tag. Most typically in Ember this function will be a compiled
      `Ember.Handlebars` template.

      ```javascript
      AView = Ember.View.extend({
        template: Ember.Handlebars.compile('I am the template')
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view">I am the template</div>
      ```

      Within an Ember application is more common to define a Handlebars templates as
      part of a page:

      ```html
      <script type='text/x-handlebars' data-template-name='some-template'>
        Hello
      </script>
      ```

      And associate it by name using a view's `templateName` property:

      ```javascript
      AView = Ember.View.extend({
        templateName: 'some-template'
      });
      ```

      If you have nested resources, your Handlebars template will look like this:

      ```html
      <script type='text/x-handlebars' data-template-name='posts/new'>
        <h1>New Post</h1>
      </script>
      ```

      And `templateName` property:

      ```javascript
      AView = Ember.View.extend({
        templateName: 'posts/new'
      });
      ```

      Using a value for `templateName` that does not have a Handlebars template
      with a matching `data-template-name` attribute will throw an error.

      For views classes that may have a template later defined (e.g. as the block
      portion of a `{{view}}` Handlebars helper call in another template or in
      a subclass), you can provide a `defaultTemplate` property set to compiled
      template function. If a template is not later provided for the view instance
      the `defaultTemplate` value will be used:

      ```javascript
      AView = Ember.View.extend({
        defaultTemplate: Ember.Handlebars.compile('I was the default'),
        template: null,
        templateName: null
      });
      ```

      Will result in instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view">I was the default</div>
      ```

      If a `template` or `templateName` is provided it will take precedence over
      `defaultTemplate`:

      ```javascript
      AView = Ember.View.extend({
        defaultTemplate: Ember.Handlebars.compile('I was the default')
      });

      aView = AView.create({
        template: Ember.Handlebars.compile('I was the template, not default')
      });
      ```

      Will result in the following HTML representation when rendered:

      ```html
      <div id="ember1" class="ember-view">I was the template, not default</div>
      ```

      ## View Context

      The default context of the compiled template is the view's controller:

      ```javascript
      AView = Ember.View.extend({
        template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
      });

      aController = Ember.Object.create({
        firstName: 'Barry',
        excitedGreeting: function() {
          return this.get("content.firstName") + "!!!"
        }.property()
      });

      aView = AView.create({
        controller: aController,
      });
      ```

      Will result in an HTML representation of:

      ```html
      <div id="ember1" class="ember-view">Hello Barry!!!</div>
      ```

      A context can also be explicitly supplied through the view's `context`
      property. If the view has neither `context` nor `controller` properties, the
      `parentView`'s context will be used.

      ## Layouts

      Views can have a secondary template that wraps their main template. Like
      primary templates, layouts can be any function that  accepts an optional
      context parameter and returns a string of HTML that will be inserted inside
      view's tag. Views whose HTML element is self closing (e.g. `<input />`)
      cannot have a layout and this property will be ignored.

      Most typically in Ember a layout will be a compiled `Ember.Handlebars`
      template.

      A view's layout can be set directly with the `layout` property or reference
      an existing Handlebars template by name with the `layoutName` property.

      A template used as a layout must contain a single use of the Handlebars
      `{{yield}}` helper. The HTML contents of a view's rendered `template` will be
      inserted at this location:

      ```javascript
      AViewWithLayout = Ember.View.extend({
        layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>")
        template: Ember.Handlebars.compile("I got wrapped"),
      });
      ```

      Will result in view instances with an HTML representation of:

      ```html
      <div id="ember1" class="ember-view">
        <div class="my-decorative-class">
          I got wrapped
        </div>
      </div>
      ```

      See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield)
      for more information.

      ## Responding to Browser Events

      Views can respond to user-initiated events in one of three ways: method
      implementation, through an event manager, and through `{{action}}` helper use
      in their template or layout.

      ### Method Implementation

      Views can respond to user-initiated events by implementing a method that
      matches the event name. A `jQuery.Event` object will be passed as the
      argument to this method.

      ```javascript
      AView = Ember.View.extend({
        click: function(event) {
          // will be called when when an instance's
          // rendered element is clicked
        }
      });
      ```

      ### Event Managers

      Views can define an object as their `eventManager` property. This object can
      then implement methods that match the desired event names. Matching events
      that occur on the view's rendered HTML or the rendered HTML of any of its DOM
      descendants will trigger this method. A `jQuery.Event` object will be passed
      as the first argument to the method and an  `Ember.View` object as the
      second. The `Ember.View` will be the view whose rendered HTML was interacted
      with. This may be the view with the `eventManager` property or one of its
      descendent views.

      ```javascript
      AView = Ember.View.extend({
        eventManager: Ember.Object.create({
          doubleClick: function(event, view) {
            // will be called when when an instance's
            // rendered element or any rendering
            // of this views's descendent
            // elements is clicked
          }
        })
      });
      ```

      An event defined for an event manager takes precedence over events of the
      same name handled through methods on the view.

      ```javascript
      AView = Ember.View.extend({
        mouseEnter: function(event) {
          // will never trigger.
        },
        eventManager: Ember.Object.create({
          mouseEnter: function(event, view) {
            // takes precedence over AView#mouseEnter
          }
        })
      });
      ```

      Similarly a view's event manager will take precedence for events of any views
      rendered as a descendent. A method name that matches an event name will not
      be called if the view instance was rendered inside the HTML representation of
      a view that has an `eventManager` property defined that handles events of the
      name. Events not handled by the event manager will still trigger method calls
      on the descendent.

      ```javascript
      OuterView = Ember.View.extend({
        template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
        eventManager: Ember.Object.create({
          mouseEnter: function(event, view) {
            // view might be instance of either
            // OuterView or InnerView depending on
            // where on the page the user interaction occured
          }
        })
      });

      InnerView = Ember.View.extend({
        click: function(event) {
          // will be called if rendered inside
          // an OuterView because OuterView's
          // eventManager doesn't handle click events
        },
        mouseEnter: function(event) {
          // will never be called if rendered inside
          // an OuterView.
        }
      });
      ```

      ### Handlebars `{{action}}` Helper

      See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action).

      ### Event Names

      All of the event handling approaches described above respond to the same set
      of events. The names of the built-in events are listed below. (The hash of
      built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
      can be registered by using `Ember.Application.customEvents`.

      Touch events:

      * `touchStart`
      * `touchMove`
      * `touchEnd`
      * `touchCancel`

      Keyboard events

      * `keyDown`
      * `keyUp`
      * `keyPress`

      Mouse events

      * `mouseDown`
      * `mouseUp`
      * `contextMenu`
      * `click`
      * `doubleClick`
      * `mouseMove`
      * `focusIn`
      * `focusOut`
      * `mouseEnter`
      * `mouseLeave`

      Form events:

      * `submit`
      * `change`
      * `focusIn`
      * `focusOut`
      * `input`

      HTML5 drag and drop events:

      * `dragStart`
      * `drag`
      * `dragEnter`
      * `dragLeave`
      * `dragOver`
      * `dragEnd`
      * `drop`

      ## Handlebars `{{view}}` Helper

      Other `Ember.View` instances can be included as part of a view's template by
      using the `{{view}}` Handlebars helper. See [Ember.Handlebars.helpers.view](/api/classes/Ember.Handlebars.helpers.html#method_view)
      for additional information.
