/* Tree 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.
