  * Decription :- This js file is used to get the courselist from the server and displays the course catalog.
  * It communicates between the server and client by sending the XMLHTTPRequest object for getting course list 
  * by receiving the response object and also when the user clicks on the product or SCO. 
  * This is also implemented for expanding and collapsing the course list.
