class HRichCorrelatorSim: public HRichCorrelator

  cout<<"in reinit function"<<endl;

 function that prints the found GEANT track numbers
 for different detector hits in a HHitMatchSim obj

 temp helper arrays to hold GEANT track numbers and their weights
 need to be reset as they are data members
 GEANT starts track numbers at 1, therefore init them to 0

 copy GEANT track info from the hit

 according to info from Vladimir Pechenov
 copy GEANT track info from the hit

 look in HShowerTrack and HShowerHitTof
 and match the info
 basically what is done in HShowerHitTofMatcher
 but there for each GEANT track number one clone is created
 which is not useful here --- > we do it ourselves

 all possible RICH MDC META bi correlations are done
 now check whether there is a tri correlation of GEANT track numbers

 look if we find the same GEANT track number for
 the rich hit and the hit in shower or tof

 use the number of fired pads in a ring per tracknumber as
 a confidence value for this track number

 use number of drift times that have contributed to this segment
 and that come from one GEANT number as confidence value

check if geant nb is already stored
we store only a maximum of MAXPARTICLES particles,
the rest is discarded

check if geant nb is already stored

this func needs two indexes as we need to find the weight for both rich and mdc
check if geant nb is already stored

 returns 1 if track nb corresponds to a lepton from pi0 Dalitz decay
 else returns zero

 returns 1 if track nb corresponds to a lepton from gamma conv
 else returns zero

check whether the particle with GEANT track number trk
has reached the MDC module 0, layer 0
this means that it didn't hit a spoke or edge in the RICH
and can therefore be correlated and detected, finally going
in efficiency.
returns 1 if particle was seen in MDC, or 0 else
trknb is return value of isLepOnMirror, the track number of
the first found lepton passing through the mirror
matching a track number in the ring

 this function checks whether a GEANT particle correlation
 occurs for min 1 ring generating lepton in this tracklet

 this function checks whether the ring that went in the
 tracklet contains pads fired by photons that come from a lepton
 one should also check whether the lepton reached the mirror
 and the first MDC module
