/*  
File Name: newRef.js 
Ver.No.: 0.1.8
NOTE: Service Schedule is now live. Offline Service Page is also implemented.

Bugs Removed:
1) If a visitor who has already chatted once starts a chat and then switches the page, was unable to view his/her chat after page switching.
   This issue is now resolved.
Features Added:
none
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 ChatScript.js currently they are placed in this file.
