Overview

This class is a helper to VR::ListView and VR::TreeView. When

colums are created, this class is used as the renderer because
it adds functionality to the Gtk Renderer.

When you call ListView#render(model_col) an instance of this class
will be returned.  It is a subclass of Gtk::CellRendererText

So it has all the functionality of its parent, plus the methods listed here.
