-// TreeNodeModel and TreeNodes provide an implementation of TreeModel around
-// TreeNodes. TreeNodes form a directed acyclic graph.
-//
-// TreeNodes own their children, so that deleting a node deletes all
-// descendants.
-//
-// TreeNodes do NOT maintain a pointer back to the model. As such, if you
-// are using TreeNodes with a TreeNodeModel you will need to notify the observer
-// yourself any time you make any change directly to the TreeNodes. For example,
-// if you directly invoke SetTitle on a node it does not notify the
-// observer, you will need to do it yourself. This includes the following
-// methods: SetTitle, Remove and Add. TreeNodeModel provides cover
-// methods that mutate the TreeNodes and notify the observer. If you are using
-// TreeNodes with a TreeNodeModel use the cover methods to save yourself the
-// headache.
-//
-// The following example creates a TreeNode with two children and then
-// creates a TreeNodeModel from it:
-//
-// TreeNodeWithValue<int> root = new TreeNodeWithValue<int>(0, L"root");
-// root.add(new TreeNodeWithValue<int>(1, L"child 1"));
-// root.add(new TreeNodeWithValue<int>(1, L"child 2"));
-// TreeNodeModel<TreeNodeWithValue<int>>* model =
-//     new TreeNodeModel<TreeNodeWithValue<int>>(root);
-//
-// Two variants of TreeNode are provided here:
-//
-// . TreeNode itself is intended for subclassing. It has one type parameter
-//   that corresponds to the type of the node. When subclassing use your class
-//   name as the type parameter, eg:
-//   class MyTreeNode : public TreeNode<MyTreeNode> .
-// . TreeNodeWithValue is a trivial subclass of TreeNode that has one type
-//   type parameter: a value type that is associated with the node.
-//
-// Which you use depends upon the situation. If you want to subclass and add
-// methods, then use TreeNode. If you don't need any extra methods and just
-// want to associate a value with each node, then use TreeNodeWithValue.
-//
-// Regardless of which TreeNode you use, if you are using the nodes with a
-// TreeView take care to notify the observer when mutating the nodes.
