// JavaScript 
// provides simple pagination functions
// requieres : jquery-1.2.3.js
// usage  setPagination(<#page[pageNum]>)  (defaults to #page1)
// pages are divs with id=page[pagenumber] and class=page
// pages should be initially set to display:none 	
// additional styles can be set for pagination using:
//		id = 'pagination'   - The pagination div itself
// 		class = 'paginationLink' - the links to the  pages
// 				'currentPage' - the current page span tag
