/**
* I use the BaseCommand class to encapsulate data used to make an Rx Observable call.
* An Rx call usually combines the action of saving a model object to firebase, 
* converting the model to a RealmObject and also saving to Realm into one atomic function flow with 
* an EventCallback. BaseCommands are posted from any Fragment or Activity with ProxyApplication.java's 
* getRxBus().post() method. The BaseCommand is then processed in ProxyApplication which creates an 
* IntentService to call the posted BaseCommand's interface ExecuteCommand, "execute()" method. 
* This returns a list of events, List<EventCallback>, which contain the updated user data to 
* post to subscribers of the event type.
