If you are going to be doing anything but simple add/remove operations
on your ComboBox's entries, then you should instead use your own
model, since the base TreeModel interface is read-only.  Look at
creating a ListStore (new ListStore(typeof(string))).  That model
should give you all the methods you need to do what you want.
