TreeController class
Controls the tree index. It uses a list of indexes, so that it can set the node index. The first indexes are for the parent nodes, and last index is for the child node. For example, the tree:
Page Menus Home Profile User Search Settings
the list 1, 1, 0 would set the User page.
