	*****************************************
	GENERAL NOTES:
	*****************************************
	
	The following javascript functionality serves in conjunction with the videoPlayer and carousel
	flash components. There are a number of functions that need to be called between flash and
	javascript, a naming convention has been implemented to indicate which is which.
	
	"js_" indicates functions that are called from flash to javascript
	"fl_" indicates functions that are called from javascript to flash
	
	ADD THIS:
	The video player uses the 'addThis' widget to display a dropDown widget. AddThis isn't designed to
	work automatically with flash content so there are a number of functions dedicated to getting it to
	work appropriately
