function uc_treeNode::add_child in Ubercart 5
Determines if new child is an immediate descendant or not.
This function is completely dependent on the structure of the array returned by taxonomy_get_tree(). Each element in the array knows it's depth in the tree and the array is a preorder iteration of the logical tree structure. Therefore, if the parameter is more than one level deeper than $this, it should be passed to the last child of $this.
