/**
* Convert a <1.3 tree into a 1.3 tree format
*
* This will convert the tree into a format needed for some new features in
* 1.3. Your <1.3 tree will still work without converting but some new features
* like preorder sorting won't work as expected.
*
* <pre>
* Usage:
* - Create a new node table (tb_nodes2) from the current node table (tb_nodes1) (only copy the structure).
* - Create a nested set instance of the 'old' set (NeSe1) and one of the new set (NeSe2)
* - Now you have 2 identical objects where only node_table differs
* - Call DB_NestedSet::convertTreeModel(&$orig, &$copy);
* - After that you have a cleaned up copy of tb_nodes1 inside tb_nodes2
* </pre>
*
* @param object DB_NestedSet $orig Nested set we want to copy
* @param object DB_NestedSet $copy Object where the new tree is copied to
* @param integer $_parent ID of the parent node (private)
*
* @static
* @access public
* @return bool True uns success
