/*
* AngularJs Fullcalendar Wrapper for the JQuery FullCalendar
* API @ http://arshaw.com/fullcalendar/
*
* Angular Calendar Directive that takes in the [eventSources] nested array object as the ng-model and watches (eventSources.length + eventSources[i].length) for changes.
* Can also take in multiple event urls as a source object(s) and feed the events per view.
* The calendar will watch any eventSource array and update itself when a delta is created
* An equalsTracker attrs has been added for use cases that would render the overall length tracker the same even though the events have changed to force updates.
*
