GtkBuildable allows objects to extend and customize their deserialization
from [GtkBuilder UI descriptions][BUILDER-UI].
The interface includes methods for setting names and properties of objects,
parsing custom tags and constructing child objects.

The GtkBuildable interface is implemented by all widgets and
many of the non-widget objects that are provided by GTK+. The
main user of this interface is 'GI.Gtk.Objects.Builder.Builder'. There should be
very little need for applications to call any of these functions directly.

An object only needs to implement this interface if it needs to extend the
'GI.Gtk.Objects.Builder.Builder' format or run any extra routines at deserialization time.
