//function to load info to different parts of the intranet home page
//	via javascript & xmlhttprequest (a.k.a. AJAX)
//
//	Brief description of how this code works
//	1. user clicks link on homepage with a javascript function
//	2. javascript function uses XMLHTTPRequest to make HTTP request
//	   (variables determine what page is requested & where to place it on the page)
//	3. HTML returned from the request is placed on the page where specified
//	   (HTML id specifies where to place it on the page)
