 Meaning of HMdcGeantTrack::trackStatus, HMdcGeantSeg::segmentStatus
 and HMdcClusSim::trackStatus[tr] bits.

 Bits in HMdcGeantTrack::trackStatus:

  Bit 8, GEANT_BUG          : =0 - GEANT bug was found in this track
  Bit 7, NO_META_HIT        : =0 - track don't reach META
  Bit 6, NOT_RECONSTRUCTABLE: =0 - not reconstructable track. It can be if
                                   track not present in mdc,
                                   track cross more then one sector,
                                   numder of segments <1 or >2,
                                   upstream direction of at list one segment,
                                   track doesn't cross inner or outer segment,
                                   num. of segments with digi.wires <1 or >2,
                                   num.digi.wires in track < 5*num.segments,
                                   at list one seg. has <3 layers or <5 wires
  Bits 1-5 are eq.1

 Bits in HMdcGeantSeg::segmentStatus trackStatus bits plus:

  Bit 5, SEG_NOT_RECONS_ABLE: =0 - segment has <3 layers or <5 digi.wires
  Bit 4, HIT_NOT_RECONS_ABLE: =0 - at list one mdc in segment has
                                   <3 fired layers or <5 wires

 Bits in HMdcClusSim::trackStatus[tr] are segmentStatus bits plus:

  Bit 3, CLFLEVEL_TOO_HIGH  : =0 - segment can't be found due to high level
                                   of cluster finder
  Bit 2, FAKE_CONTRIBUTION  : =0 - fake contribution in cluster
  Bit 1, SEGS_MATH_OK       : =0 - no inner-outer segments matching
