Extending Cakephp 3 with an additional Behaviour

Cakephp3 provides the TreeBehavior with its core. [login to view URL] I need someone to create a similar behaviour, but the Tree I need is not a strict hirarchy like in TreeBehavior. The Tree I need allows childs to have multiple parents and parents to have multiple chields. The Models, which have this behaviours are self-relational by n:m. This means the new behaviour works with the table of the Model and a small Table safing the connections, Additionally I would like the new Behaviour not to delete previous Trees by enabeling an option. Instead of deletion this behaviour should save the timestamp when the relation was set and when it was disabled. Project must be delivered with a documentation similar to this one: [login to view URL] Following functions must be supplied to use with find(): - children (usage and result should be similar like 'children' from TreeBehaviour) - parents (usage and result should be similar like 'children' from TreeBehaviour) - childCount (usage and result should be similar like 'childCount' from TreeBehaviour) - parentCount (usage and result should be similar like 'childCount' from TreeBehaviour) - childList (usage and result should be similar to 'treeList' from TreeBehaviour) - parentList (usage and result should be similar to 'treeList' from TreeBehaviour) - findPath will now return the paths to all parents - removeFromTree (as in TreeBehaviour) - moveUp (as in TreeBehaviour, but requires the parent which will be the new sister) - moveDown (as in TreeBehaviour, but requires the child which will be the new sister) - getLevel (returns every root parent and the levels it goes there) This new behaviour must take care, that no one is building a circle into this: Following example is never allowed to happen: ID = 1 is child of 2, ID = 2 is child of 3, ID = 3 is child of 1 Task is given away due to a lack of time. Your code should be submitted to the Cakephp project so it might be accepted and continued to be maintained. It should be build the same way like CakePHP and follow the same conventions.
