    Filename: 	linktrack_funcs.js 
	Purpose:  	clientside tracking functionality. Reads flattened SED CMS html pages and transforms
				all links within the page with tracking data by replacing CMS created placeholders with channel / page info. 
				Also contains a method for tracking form submitions. All code is based on orginally cminclude.js file
				within the wanadooo portal.
