/**********************************************
	Number based pagination
	
	This script takes any block level element,
	and a maximum height, and splits the element
	into pages. 
	
	These pages can be paginated through by
	the dynamically generated number links. 
	
	It adds the links to any subelements with a
	class of .number-pagination
	
	This script requires jQuery.
