 * Cleanup. All known bugs fixed
 *
 * Revision 2.48  2004/12/02 22:14:53  calderon
 * Only fill the fitTraits.chi2[1] data member for primaries.
 * It holds node->getChi2() from the innerMostHitNode, which will be the
 * vertex for primaries.
 *
 * Revision 2.47  2004/12/02 04:18:06  pruneau
 * chi2[1] now set to incremental chi2 at inner most hit or vertex
 *
 * Revision 2.46  2004/12/01 15:35:46  pruneau

 *
 * Revision 2.45  2004/11/08 15:34:16  pruneau

 *
 * Revision 2.44  2004/10/27 03:25:54  perev
 * Version V3V
 *
 * Revision 2.43  2004/10/26 06:45:41  perev
 * version V2V
 *
 * Revision 2.42  2004/10/14 02:21:34  calderon
 * Updated code in StTrackDetectorInfo, now only increment the reference count
 * for globals, not for primaries.  So fillTrackDetectorInfo changed to reflect
 * this.
 *
 * Revision 2.41  2004/10/01 01:13:51  calderon
 * Added bug fix from Marco:
 * flag%100 -> flag/100.
 *
 * Revision 2.40  2004/08/17 20:04:28  perev
 * small leak fixed, delete physicalHelix,originD
 *
 * Revision 2.39  2004/08/17 04:53:05  calderon
 * When filling fit traits for primary tracks, set the new flag
 * mPrimaryVertexUsedInFit.
 *
 * Revision 2.38  2004/08/10 14:21:13  calderon
 * Use the firstHit from the dynamic_cast, to avoid a compiler warning
 * for an unused variable.
 *
 * Revision 2.37  2004/08/06 22:23:29  calderon
 * Modified the code to use the setNumberOfxxxPoints(unsigned char,StDetectorId)
 * methods of StTrack, StTrackDetectorInfo, StTrackFitTraits, and to use
 * the maxPointCount(unsigned int detId) method of StiKalmanTrack.
 *
 * Revision 2.36  2004/08/06 02:29:20  andrewar
 * Modifed call to getMaxPointCount
 *
 * Revision 2.35  2004/08/05 05:25:25  calderon
 * Fix the assignment of the first point for primaries.  Now,
 * the logic for both globals and primaries is that the first
 * point is the first element of the stHits() vector that
 * can actually be casted to an StHit (the vertex will fail this test,
 * all other hits coming from detectors will satisfy it).
 *
 * Revision 2.34  2004/07/30 18:49:18  calderon
 * For running in production, Yuri's dEdx Maker will fill the Pid Traits,
 * so the filling of Pid Traits in the filler is no longer needed:
 * it actually causes confusion because the V0 finders will loop over
 * the PID traits vector and find the first one, so they won't find
 * the trait created by the dEdx Maker.  It is best to just comment
 * out the filling of the Pid Traits here.
 *
 * Revision 2.33  2004/07/07 19:33:48  calderon
 * Added method fillFlags.  Flags tpc, tpc+svt (globals and primaries) and flags -x02 tracks with less than 5 total fit points
 *
 * Revision 2.32  2004/04/21 21:36:24  calderon
 * Correction in the comments about the encoded method.
 *
 * Revision 2.31  2004/03/31 00:27:29  calderon
 * Modifications for setting the fit points based on the chi2<chi2Max algorithm.
 * -Distinguish between points and fit points, so I added a function for each.
 * -Points is done as it was before, just counting the stHits for a given
 *  detector id.
 * -Fit points is done the same with the additional condition that each
 *  StiKalmanTrackNode has to satisfy the chi2 criterion.
 *
 * Revision 2.30  2004/03/29 00:52:20  andrewar
 * Added key value to StTrack fill. Key is simply the size of the
 * StTrackNode container at the time the track is filled.
 *
 * Revision 2.29  2004/03/23 23:12:36  calderon
 * Added an "accept" function to filter unwanted tracks from Sti into StEvent.
 * The current method just looks for tracks with a negative length, since
 * these were causing problems for the vertex finder (length was nan).  The
 * nan's have been trapped (one hopes!) in StiKalmanTrack, and for these
 * cases the return value is negative, so we can filter them out with a
 * simple length>0 condition.
 *
 * Revision 2.28  2004/03/19 19:33:23  andrewar
 * Restored primary filling logic. Now taking parameters at the
 * vertex for Primary tracks.
 *
 * Revision 2.27  2004/01/27 23:40:46  calderon
 * The filling of the impactParameter() for global tracks is done now
 * only after finding the vertex.  The
 * StPhysicalHelix::distance(StThreeVectorD) method is used for both globals
 * and primaries, the only difference is where the helix is obtained:
 * - globals - helix from StTrack::geometry(), which was filled from the
 *             innermost hit node, which should be a hit at the time.
 * - primaries - helix from innermost hit node, which should be the vertex
 *             at the time it is called.
 *
 * Revision 2.26  2003/12/11 03:44:29  calderon
 * set the length right again, it had dissappeared from the code...
 *
 * Revision 2.25  2003/11/26 04:02:53  calderon
 * track->getChi2() returns the sum of chi2 for all sti nodes.  In StEvent,
 * chi2(0) should be chi2/dof, so we need to divide by
 * dof=track->getPointCount()-5;
 *
 * Revision 2.24  2003/09/07 03:49:10  perev
 * gcc 3.2 + WarnOff
 *
 * Revision 2.23  2003/09/02 17:59:59  perev
 * gcc 3.2 updates + WarnOff
 *
 * Revision 2.22  2003/08/21 21:21:56  andrewar
 * Added trap for non-finite dEdx. Added logic to fillGeometry so
 * info is for innerMostHitNode on a detector, not vertex (note:
 * Primaries only)
 *
 * Revision 2.21  2003/08/05 18:26:15  andrewar
 * DCA track update logic modified.
 *
 * Revision 2.20  2003/07/01 20:25:28  calderon
 * fillGeometry() - use node->getX(), as it should have been since the
 * beginning
 * impactParameter() - always use the innermos hit node, not just for globals
 * removed extra variables which are no longer used.
 *
 * Revision 2.19  2003/05/15 03:50:26  andrewar
 * Disabled call to filldEdxInfo for the SVT. Checks need to be
 * applied to make sure the detector is active before calculator
 * is called, but for the review filling this info is unnecessary.
 *
 * Revision 2.18  2003/05/14 00:04:35  calderon
 * The array of 15 floats containing the covariance matrix has a different
 * order in Sti than in StEvent.  In Sti the array is counted starting from
 * the first row, column go to next column until you hit the diagonal,
 * jump to next row starting from first column. In StEvent the array is
 * counted starting from the first row, column go to the next row until you
 * hit the end, jump to next column starting from diagonal.
 * The filling of the fitTraits was fixed to reflect this.
 *
 * Revision 2.17  2003/05/12 21:21:39  calderon
 * switch back to getting the chi2 from track->getChi2()
 * Covariance matrix is still obtained from node->get(), and the values
 * are not as expected in StEvent, so this will still need to change.
 *
 * Revision 2.16  2003/05/08 22:23:33  calderon
 * Adding a check for finiteness of node origin and node curvature.  If any
 * of the numbers is not finite, the code will abort().
 *
 * Revision 2.15  2003/04/29 18:48:52  pruneau
 * *** empty log message ***
 *
 * Revision 2.14  2003/04/29 15:28:10  andrewar
 * Removed hacks to get helicity right; switch now done at source
 * (StiKalmanTrackNode).
 *
 * Revision 2.13  2003/04/25 21:42:47  andrewar
 * corrected DCA bug and added temp fix for helicity problem. This will
 * have to be modified when the helicity convention in StiStKalmanTrack
 * is updated.

 * *** empty log message ***
 *
 * Revision 1.5  2002/04/09 16:03:13  pruneau
 * Included explicit extension of tracks to the main vertex.
 *
 * Revision 1.4  2002/04/03 16:35:03  calderon
 * Check if primary vertex is available in StiStEventFiller::impactParameter(),
 * if not, return DBL_MAX;
 *
 * Revision 1.3  2002/03/28 04:29:49  calderon
 * First test version of Filler
 * Currently fills only global tracks with the following characteristics
 * -Flag is set to 101, as most current global tracks are.  This is not
 * strictly correct, as this flag is supposed to mean a tpc only track, so
 * really need to check if the track has svt hits and then set it to the
 * appropriate flag (501 or 601).
 * -Encoded method is set with bits 15 and 1 (starting from bit 0).  Bit 1
 * means Kalman fit.
 *  Bit 15 is an as-yet unused track-finding bit, which Thomas said ITTF
 * could grab.
 * -Impact Parameter calculation is done using StHelix and the primary vertex
 * from StEvent
 * -length is set using getTrackLength, which might still need tweaking
 * -possible points is currently set from getMaxPointCount which returns the
 *  total, and it is not
 *  what we need for StEvent, so this needs to be modified
 * -inner geometry (using the innermostHitNode -> Ben's transformer ->
 *  StPhysicalHelix -> StHelixModel)
 * -outer geometry, needs inside-out pass to obtain good parameters at
 *  outermostHitNode
 * -fit traits, still missing the probability of chi2
 * -topology map, filled from StuFixTopoMap once StDetectorInfo is properly set
 *
 * This version prints out lots of messages for debugging, should be more quiet
 * when we make progress.
