Class Description

 Class BrMrsTofMatchingModule

 Module scanning the global track table and picking up those
 matching valid tof hits.
 Selected pairs saved into table of BrTofTrackMatch named "MRS Matching"

 Algorithm (Event method):
 -------------------------

 1- pick up tables of TOFW hits and MRS tracks
    if one of them missing, return

 2-
    a- Select tof hits by checking the TDCs and ADCs of both tubes

    b- loop over tracks and sub-loop over hits
          i - evaluate the dX between track projection and hit position
         ii - minimize this distance and store the "winner" hit
              slat number in an array that has the dimension of
              the track table. It might be that the minimal dX is
              beyond the matching criterium, then, the hit id is -1

    c- check "multiple hits" when more than 1 track share the same
       hit. In that case, ignore these tracks (it doesn't remove
       completely multiple hits since there might be one track
       only pointing to such hits - the other tracks having not
       been reconstructed)

    d- loop over remaining matchings and store result into table
       of BrTofTrackMatch object (cf class implementation file)

    Note: due to the problem in the TPM2 tracks (slopes) that causes tracks to
    be off at the slats at the edge, an effective correction to the hit pos is introduced.
    to correct the Hit - used in finding the 'best' hit.
