05/18/2007, jstrimpe@soe.ucsd.edu: Created by Jason Strimpel for the CCSD web site.
For any help with this file send mail to dehelp@soe.ucsd.edu.

This file determines the current URL of a user's browser and sets the child header
image HTML and creates the appropriate sub navigation menu. Expanded versions of the menus 
are commented out so that they can be easily read as opposed to one long string that is
used by the variable MenuHTML. 

SiteRoot is used to define the root of the web site. "/" can be used if the web site has 
it's own URL. This variable was added so that moving the site into production would be much easier.

The function SubMenu() is called by all child pages.

To updated a child menu or image change the coded for the appropriate section below.
