ACD Recon Update to Event Display

ACD recon information as visualized in Fred

 Hits and Digis

Every hit tile and ribbon is represented by highlighting the outline of the tile or ribbon as seen by the AcdGeometrySvc.  For ribbons this is slightly simplified relative to the GEANT model as small segements are excluded.  The advantage of this is that it can be used to debug the reconstruction by show the geometry exactly as it is seem by the reconstruction algorithms.

 Here as some examples

 Track extrapolations and ACD associations (AcdTkrAssoc)

 Associations with Hit Tiles (AcdTkrHitPoca with signals)

 Associations with Gaps (AcdTkrGapPoca)

 Intersections with GEANT model (call AcdTkrIntersection, but filled from AcdTkrHitPoca w/ no signals)
