/**

* @title: GtkApplication
* @short_description: Application class
*
* #GtkApplication is a class that handles many important aspects
* of a GTK+ application in a convenient fashion, without enforcing
* a one-size-fits-all application model.
*
* Currently, GtkApplication handles application uniqueness, provides
* some basic scriptability by exporting 'actions', implements some
* standard actions itself (such as 'Quit') and provides a main window
* whose life-cycle is automatically tied to the life-cycle of your
* application.
*
