    Page Based Highlighting is intended to be used with
    non-home page submenus. The script determines the 
    page based on the URL and checks it directly against 
    the href attribute of registered menu elements.
    
    If the href attribute is found in the url string then
    the element is granted a pre-determined style.'
    
    * Keep in mind that using server side resolution of urls 
    in ASP.NET 2.0 will result in altered IDs. 
    
    ** Also, using relative pathing will be helpful here
    in creating portability of this javascript.
