3840N/A * SampleTreeModel extends JTreeModel to extends valueForPathChanged.
3840N/A * This method is called as a result of the user editing a value in
3840N/A * the tree. If you allow editing in your tree, are using TreeNodes
3840N/A * and the user object of the TreeNodes is not a String, then you're going
3840N/A * to have to subclass JTreeModel as this example does.
