/* List View/List Store
*
* The Gtk.ListStore is used to store data in tree form, to be
* used later on by a Gtk.ListView to display it. This demo builds
* a simple Gtk.ListStore and displays it. If you're new to the
* Gtk.ListView widgets and associates, look into the Gtk.ListStore
* example first.
