//        In the body of your document put: <SCRIPT Language="JavaScript">HNav()</script>
//      * Change the BaseURL1 to your base URL.
//      * Though not necessary, if using a betatest site or two hosts or any form of second host,
//        change the BaseURL2 to that URL. BaseURL2 can be left blank.
//      * This script draws on your folder names. Good names = good navigation. Bad names = bad navigation.
//      * In lieu of spaces in folder names, you can use the underscore character.
//      * the var 'IndexFile' is used if you want to use something other than 'index.htm' in your folder
//        structure. For example, 'Home.htm'. If you do use index.htm or index.html (or whatever the
//        server automatically assigns), blank out IndexFile to ''.
