    changes : 18/7/07 deleted all references to Track / TrackParticleBase origin
              since new EDM automatically deals with it... (thanks to Kirill/Andi's new LinkToTrack/
              LinkToTrackParticle)

              Vertex objects stored in this class are now xAOD::Vertex (from Trk::VxCandidate)
