 *
 * Description: Allow to cut on hit merging         
 * Usage :
 *  HitMergingPairCut* pairCut = new HitMergingPairCut();
 *  pairCut->setDefaultHalfFieldMergingPar();
 *  pairCut->setMaxFracOfMergedRow(MaxMergedHit);

 * Revision 1.2  2003/09/02 17:58:21  perev
 * gcc 3.2 updates + WarnOff
 *
 * Revision 1.1  2001/12/14 23:11:27  fretiere
 * Add class HitMergingCut. Add class fabricesPairCut = HitMerginCut + pair purity cuts. Add TpcLocalTransform function which convert to local tpc coord (not pretty). Modify StHbtTrack, StHbtParticle, StHbtHiddenInfo, StHbtPair to handle the hit information and cope with my code
