* - 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
