/** @file bus-term.hpp
 ** Attachment point to the UI-Bos.
 ** Every gui::model::Tangible holds a BusTerm, which is linked
 ** to the Tangible's identity, and serves to relay interface actions
 ** towards the Proc-Layer. Moreover, the BusTerm is the service point
 ** to receive structural change messages.
 ** 
 ** @todo as of 11/2015 this is complete WIP-WIP-WIP
 ** 
 ** @see ////TODO_test usage example
