\brief The class eZContentObjectTreeNode does
\verbatim
Some algorithms
----------
1. Adding new Node
Enter 1 - parent_node
2 - contentobject_id, ( that is like a node value )
(a) - get path_string, depth for parent node to built path_string and to count depth for new one
(c) - calculating attributes for new node and inserting it
Returns node_id for added node
2. Deleting node ( or subtree )
Enter - node_id
3. Move subtree in tree
Enter node_id,new_parent_id
4. fetching subtree
