//* ====================
//*  ANLVTXTagger Class
//* ====================
//*
//* (Description)
//*    A very primitive vertex tagging class.
//* (Requires)
//*     class ANLJetFinder
//*     class ANLTrack
//*     class JSFSIMDST, etc.
//* (Provides)
//*     class ANLVTXTagger
//* (Update Recored)
//*    1999/10/09  K.Fujii      Original version.
//*    1999/10/18  K.Ikematsu   Implement Ks, Lambda, Sigma removal.
//*    2000/03/18  K.Ikematsu   Added SetNsig and SetNoff method.
//*    2000/03/18  K.Ikematsu   Added GetNsig and GetNoff method.
//*    2001/07/13  K.Ikematsu   Added public Getb method.
//*    2001/07/31  K.Ikematsu   Removed CDCTrack pointer
//*                             from neutral track in mixed CAL cluster.
//*                             (This causes double count of helix tracks)
