Class Description

HShowerHitTrackMatcher

 HShowerHitTrackMatcher reconstructor searches
 data describing the same pad in HShowerHit and HShowerTrack categories
 and join its to one object.
 Results are stored in HShowerHitTrack category

 The Shower task is split into several tasks as shown
 in the flow diagram below.

  In the case of TRACK EMBEDDING of simulated tracks into
  experimental data the real data are written by the HShowerUnpacker into
  HShowerRaw category. The real hits are taken into
  account by the digitizer (adding of charges). The embedding mode is recognized
  automatically by analyzing the
  gHades->getEmbeddingMode() flag.
            Mode ==0 means no embedding
                 ==1 realistic embedding (first real or sim hit makes the game)
                 ==2 keep GEANT tracks   (as 1, but GEANT track numbers will always
                     win against real data. besides the tracknumber the output will
                     be the same as in 1)

 creates the ShowerHit, ShowerTrack and ShowerHitTrack categories
 and adds them to the current event
 creates an iterator which loops over all local maxima
 and an iterator which loops over all track number information

create one object, which contains data
from HShowerHit and HShowerTrack objects

searching all pairs in HShowerHit and HShowerTrack, which
have the same address
Because HShowerHit and HShowerTrack are sorted by m_nAddress
reading data in tables is done once!
