/**
* HTML_TreeMenu Class
*
* A simple couple of PHP classes and some not so simple
* Jabbascript which produces a tree menu. In IE this menu
* is dynamic, with branches being collapsable. In IE5+ the
* status of the collapsed/open branches persists across page
* refreshes.In any other browser the tree is static. Code is
* based on work of Harald Radi.
*
* Usage.
*
* After installing the package, copy the example php script to
* your servers document root. Also place the TreeMenu.js and the
* images folder in the same place. Running the script should
* then produce the tree.
*
* Thanks go to Chip Chapin (http://www.chipchapin.com) for many
* excellent ideas and improvements.
