-/**
-* 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.
