Homework:
---------
In classs you learned about IIFE's, encapsulation and object oriented programming. 
You also worked on a example calling library_a.render() and library_b.render(). 

IIFE's are good for grouping related code in a namespace. Let's say that you have some math related functions . Then 
you could do:

var Math = (function () {
    return {
        Rectangle: function (height, width) {
            return {
               calcArea: function () {
                 return height*width;
               }
            };
        },
        Triangle: function (A, B, C) {
           // .. insert code here ...                                                                                                                                                
        }
    };
})();

var rectangle = new Math.Rectangle(10,10);
console.log(rectangle.calcArea());
var triangle = new Math.Triangle(6,8,10);
//console.log(triangle.calcArea()); 

Your task: insert code into the Math.Triangle class that 
will make console.log(triangle.calcArea()) print out the area of a triangle
