/** @file ui-bus.hpp
 ** Under construction: the top level UI controller.
 ** The Lumiera GTK GUI is built around a generic backbone structure known as **UI-Bus**.
 ** This is a messaging system and taps into any widget of more than local relevance.
 ** To that end, any globally relevant (custom) widget, and all secondary controllers
 ** inherit from the gui::model::Tangible base. The top-level gui::UiBus element is
 ** a front-end and framework component managed by the [GTK-main][GtkLumiera::main].
 ** 
 ** @warning as of 12/2015, this is still totally a mess. This \em will remain
 **          the one-and-only master controller of the UI, but I am determined
 **          to change the architecture and implementation technique altogether.
 **          For the time being, we keep the controller::Controller in place, as
 **          written by Joel Holdsworth, while building the new UI-Bus frontend
 **          to take on this central role eventually.
 ** 
 ** 
 ** @todo as of 1/2015, this needs to be reshaped ////////////////////TICKET #959
