		date: 12/30/08
		
		This calendar takes events and displays them in a month view. 
		Event types include Single Day events, All Day events, and span events.
		Each event shows a mouseover with the event title and brief summary
		Clicking on events generate a container that pulls in the event data with an ajax call.
		You can navigate months by the previous and next arrows as well as a dropdown by clicking
		on the month name.
