	Info: rpH is our Resolve Position Handler.
	
	Requires:
		library.js - browserDetect and windowOffsetY functions (Included Above)
		
	You can programatically stop the accordion from moving with the page by changing the class of the scrollerContainer to accordionStatic.
	
	Tested to work in: 	IE7 +
						Firefox
						Safari
