Class Description

 HShowerHitDigitizer

 This class digitizes  Pre-Shower wires. The value of the charge and
 its position
 on the sense wire are calculated. Due to do it there are needed geometry
 and digitisation parameters.
 These data are stored in HShowerGeantWire category.

 The Shower digitization 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, sorting by first hit in
  photo multiplier). 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 GeantShower(input) and ShowerGeantWire(output) categories
 and adds them to the current event
