* 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 it deeply 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 change is made.
*
