//	This javascript automatically makes page view calls to the GA server.
//	As well, it tags file downloads and external links in Google Analytics.
//	You need to be using the Google Analytics New Tracking Code (ga.js) 
//	for this script to work.
//	To use this file, place the script reference to this file on all pages just below the
//	Google Analytics code that includes GA.js.  See the accompanying example file prweb_basic_tracking.html
//
//	For automatic file download and external link tracking, a call to gaTagConfig must be made in the on-page code
//	The code is executed by a call to startListening as in the following example code:
//	startListening(window, ‘load’, function () {gaTagConfig(‘pdf’, false, false, false);});
//	This will attach event listeners to the correct links AFTER the page has loaded, thus ensuring all
//	links are tagged
//	All outbound links and links to non-html files should now be automatically tracked.
//	Please see the accompanying file prweb_pdf_tracking.html for an example.
