/*********************************************************************************************************


	This Script is designed to aid a Test & Target Campaign with button or link click reporting. 

	ARRAY clickEventFuncts
	Description: This Array stores the original onclick event function of the links and buttons. 
	Do not manually add to this array, because there is a function that assigns the values to this 
	global Array     


	FUNCTION addRecordClick

	Parameters:
	el 		(String or HTML Element) 	-> This is the HTML Id or HTML Element Object
	mbName 		(String) 			-> A Name of a mbox on the page. 
	mbParam		(String)			-> This param excepts mboxParam that is desired to be included during the mboxUpdate Function
	cb		(Function)			-> This is a call back function when the mboxUpdate is executed	
	runlast		(Boolean)			-> Determins is the mboxUpdate should be performed before or after an existing onclick function

	FUNCTION addSetsOfLinks

	Parameters:
	arl		(Array)				-> An Array or links or buttons can be passed to assign a set of links all at once
	mbName 		(String) 			-> A Name of a mbox on the page. 		 
	mbParam		(String)			-> This param excepts mboxParam that is desired to be included during the mboxUpdate Function
	runlast		(Boolean)			-> Determins is the mboxUpdate should be performed before or after an existing onclick function


	FUNCTION parseParamValue
	
	Parameters:
	v		(string)			-> url to be passed to parse out querystring value
	p		(string)			-> name of querystring to search value
