/*
Name: Window ChatScript     
Ver. No.: 0.1.17
Developed By: Umer Jafer

Future Updates: 
1) Make changes accordingly when the asp.net chat window starts working. The major change would be that the js window
should not pop up if the asp.net window is open. A solution could be to make a totally separate script for asp.net window.

//The Previous updates:
1) The Location of the Close button has been updated in the window and a minimize window and 
a maximize window button has been added.
2) All the images have been moved to wg_chatwindow folder so that it is a standard folder for webgreeter.
	
//Current Updates:
1) The path for the Images Online and offline status has been updated to exact URL i.e. http://www.webgreeter.com/wg_chatwindow/online.gif.
2) Variables for all the cookies, images and the services URLs have been added so that the code is easily manageable. 
   Variables will be placed in a separate file and not in newRef.js.

//NOTE: Message Repition is a major issue due to which Page Refresh process and page switching process is defined.
//For that The ChatId needs to be stored in a cookie right after chat starts.
//Also logic check needs to be implemented to stop this chat from being inserted as a new chat.
//Visitor Name Service is required to get a visitor name for the visitor Id.
