// $Log: BrTpcTrackCandidate.h,v $
// Revision 1.6  2002/03/20 00:41:08  cholm
// Some cosmetics
//
// Revision 1.5  2001/11/13 12:27:24  pchristi
// Made residuals persistent and fixed bugs in copyconstructor.
//
// Revision 1.4  2001/11/13 10:57:32  pchristi
// Added destructor to close memory leak (shame on me) and a copy constructor.
//
// Revision 1.3  2001/11/02 13:32:51  pchristi
// Added new class BrTrackResidual. This class deals with storing track
// residuals for good tracks.
// Removed adc calculations and informations from BrTpcTrackCandidate since
// this was done in a useless way. The adcsum information is now stored with
// the residual for each hit and it makes it possible to later make a
// truncated mean if one wishes stored in the track residual
//
// Revision 1.2  2001/08/14 19:26:23  pchristi
// Removed detructors and copy constructors where the default was ok.
//
// Revision 1.1.1.1  2001/06/21 14:55:03  hagel
// Initial revision of brat2
//
// Revision 1.1  2001/06/17 17:41:41  pchristi
// The new tracking classes.
//
