I *think* that should be explained in the docs. The basic idea is that
you don't use full=1. At that point, only the first level of the tree
is listed. You put a link for expanding a leaf of the tree:

	[page href=@@MV_PAGE@@
		form="
			memo=tree_memo
			toggle=[item-code]
		"][item-param catName][/page]

If you want to display + and - signs, and do other things, you
use autodetect=1, which gives the number of mv_children.

I am planning on working up an example that turns Yahoo-style
categories, i.e. Hand Tools:Brushes:Camel Hair into a collapsing
and expanding tree. I have done this many times before, but not with
the tree tag.
