variables. Total photo electrons, total hits of adc 1, total hits of adc 2
and total hits. With this update we have transformed the FORTRAN code of
file /engine/HTRACKING/h_trans_cer.f to /hcana/ser/THcCherenkov.cxx

NOTE: The pedestal value in ENGINE is an integer but in hcana it is a
flaoting number. So it changes the pedestal substracted vlues of adc 1
and adc 2 and the number of photo electrons of adc 1 and 2 by very small
fraction. The difference of total photo electrons between ENGINE and hcana
is not more than 0.005.

  general.param - include SOS parameter for most devices
  hcana.param - add sos versions of previous hardwired parameters
  db_run.dat - put in an angle and mometum for SOS
  output.def - include sos detectors in root tree
  hodtest.C - Add SOS spectrometer and some of its detectors

    Added variables using ENGINE names
       gen_run_number
       gen_run_starting_event
       gen_event_id_number

Inspired by ENGINE/CTP report generator
  Reports generated by
    THcAnalyzer::PrintReport(templatefilename,outputfilename)
    template is copied to output, {stuff} is replaced by the
       value of stuff.  Value can be formated with c formater, eg.
           {stuff:%.2f}
  ThcFormula added to allow more flexibility of variables.
    Can get number of times cuts pass or are called with:
       cutname.npassed (or cutname.scaler) and cutname.ncalled

  New class THcDC is whole set of wire chambers.
  THcDriftChamber is one chamber (6 planes)
  Implement space point finding from h_pattern_recognition up to point
     before where space point lists from the two chambers are combined.
  Includes
      FindEasySpacePoint   (h_find_easy_space_point)
      FindHardSpacePoints  (find_space_points)
      DestroyPoorSpacePoints (h_sp_destroy)
      SpacePointMultiwire  (h_sp_multiwire)
      ChooseSingleHit 	   (h_choose_single_hit)
      SelectSpacePoint	   (select_space_points)

Space points are arrays of structures in the THcDriftChamber class.  Will
probably need to take space points out class so that they can be looked at
at the THcDC level.

New code is only tested to see that it compiles and that space points
are sometimes found.

GN: finished debugging the hodoscope start time calculation. Results match 1-to-1 the corresponding "engine" result.

    Define constants (e.g. plane counts) that are not defined in
    the ENGINE parameter files so that the detector classes
    can be more generic.
    Hodoscope and Aerogel now pick up plane and tube counts from this file

    Register some more variables for the tree
    Clear fNelem of some arrays, not fNhits.
    Print method to print Aerogel pedestals.
    Make Pedestal analysis a bit more like the ENGINE.
    Initialize counters

Use cut file to determine what is a pedestal event.  Pedestal events
only proceed to Decode.
In Decode (Just THcHodoscope for now) loop through each plane and accumulate
pedestal data.  Calculate the pedestals at the first non-pedestal event.
Pedestals are just calculated, but nothing is done with them.
