RootItem Property

The root item for the toplevel collection of items in a tree oriented item structure. From a data structural point of view, trees should always be single rooted, even though trees in a UI often appear to be multi-rooted. Therefore, the RootItem of the NavControl is hidden from the user and API, but can be utilized when the tree needs to be treated as a single rooted tree.
