/** @file bus-controller.cpp
 ** Implementation of the UI backbone service for messaging.
 ** Any globally relevant widget or controller within the Lumiera UI
 ** is connected to the [UI-Bus][ui-bus.hpp], which is largely implemented
 ** within this compilation unit. [Clients][gui::model::Tangible] typically
 ** use the [BusTerm-Interface][bus-term.hpp] to route generic actions and
 ** receive notifications, state changes and mutations.
 ** 
 ** @note as of 11/2015 this is complete WIP_WIP
 ** @todo WIP  ///////////////////////TICKET #975
 ** 
 ** @see ////TODO_test usage example
 ** @see bus-controller.cpp implementation
