Simple Category Tree

[some name not taken]

Yes, sorry, - getting there now...

<?php
$_SESSION['category_tree']->build_deepest_level_children() ;
$_SESSION['category_tree']->retrieve_cpath() ;
$content .= $_SESSION['category_tree']->build_category_string('ul', 'li', '', 0, 2); 
?>

It's still not doing what I want, but I think this is how it should be.
