<h3>Menu TreeView Widget</h3>
<p>
The presentation differences between the default treeview widget and this
one were accomplished by modifying the css styles in tree.css. The
functionality is the same, except the menu does not allow multiple siblings
to be expanded at one time (when you expand a node, all of its expanded
siblings are collapsed.
