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