/** @file work-site-trail.hpp
 ** History of work sites visited by the user in recent past.
 ** The immediate consequence of introducing the concept of a WorkSite is the
 ** expectation for the user to navigate between several such locations within
 ** the interface space. This establishes a context of _least recently visited_
 ** locations, which can be used to resolve various contextual questions. Most
 ** notably, managing such a history allows us to _navigate back._
 ** 
 ** @todo WIP 2/2017 early draft / foundations of "interaction control"
