/*
 * GUI window header
 *
 * Top level object that manages GUI views.
 * Currently, there are four kinds of view,
 * GdiffDirView, GdiffOnepView, GdiffTwopView, and GdiffMergeView.
 * From a GUI perspective, a view is a child widget of notebook widget,
 * but this is just a current implementation.
 * (hopefully, will be replaced with GNOME MDI)
 * This module provides various interfaces for managing views.
