# the hull widget is a tk widget which is the (mega) widget handled behind the itcl
# extendedclass/itcl widget.
# It is created be renaming the itcl class object to a temporary name <itcl object name>_
# creating the widget with the
# appropriate options and the installing that as the "hull" widget (the container)
# All the options in args and the options delegated to component itcl_hull are used
# Then a unique name (hull_widget_name) in the itcl namespace is created for widget:
# ::itcl::internal::widgets::hull<unique number><namespace tail path>
# and widget is renamed to that name
# Finally the <itcl object name>_ is renamed to the original <itcl object name> again
# Component itcl_hull is created if not existent
# itcl_hull is set to the hull_widget_name and the <itcl object name>
# is returned to the caller
