TreeNode Manager

Almost all of the TreeNode manipulation features are implemented on TreeNodeManager, this help us to test, extend and change the implementation for some features if it needed.

By Default TreeViewAdapter depend on the Default TreeNodeManager class but if you want a custom implementation, you can easily create a new manager class that extend TreeNodeManager and pass it on TreeViewAdapter constructor

TreeViewAdapter adapter = new TreeViewAdapter(factory, customTreeNodeManager);

The TreeNodeManager class has many method to help easily provide features.
