// $Log: StiForwardTrackMaker.h,v $
// Revision 1.8  2007/07/12 19:27:21  fisyak
// Add includes for TMath for ROOT 5.16
//
// Revision 1.7  2005/09/26 14:03:55  kocolosk
// added Kalman propagation for forward track seeds
//
// Revision 1.6  2005/09/21 15:37:06  kocolosk
// modified matchVertex() so that |deltaZ| could be plotted separately for old, new tracks
//
// Revision 1.5  2005/09/14 14:15:14  kocolosk
// restrict to TPC hits, added histos, moved code to matchVertex() function
//
// Revision 1.4  2005/09/13 14:24:16  kocolosk
// implemented getForwardHits() and buildTrackSeeds() functions
//
// Revision 1.3  2005/09/12 21:08:21  balewski
// split Make to InSti and AfterSti
//
// Revision 1.2  2005/09/09 15:55:00  balewski
// prototype with hardcoded hacks
//
// Revision 1.1  2005/09/08 21:42:03  balewski
