/** @file fixedlocation.hpp
** Specialised LocatingPin for use in Placement, especially for globally fixed positions
** The FixedLocation is assumed to play a central role within the Build process, which
** ultimately aims ad resolving any part of the session into either a wiring directive
** or a piece of media or processing to happen at a location fixed in time.
**
** @todo stalled effort towards a session implementation from 2008
** @todo 2016 likely to stay, but expect some extensive rework
