The way I envision data bindings in TreeView is to add a DataSet
property to TreeView itself instead of exposing a public TreeModel.
Under the hood this would instantiate an internal TreeModel
implementation that binds the typed list to the TreeView and sets up all
the TreeViewColumns appropriately.

I think this approach is superior to a public TreeModel because people
who want to use data bindings are not going to want to have to format
the TreeView manually.  We already have magic in NodeView that does this
kind of auto formatting of the view.

Todd already pointed out that unless we want to write another hybrid
native/managed model like NodeStore, GInterface implementation is a
prerequisite.
