Friend the detector classes that need access to the private members.
  May later want to use member functions to access the data.

  Was hardwired to HMS, so SOS was getting HMS hodoscope data.

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.

  Fix from Mark Jones with additional cleanup for
  saw's misunderstanding of space point criterion

  Compare wire coordinate, not wire number

  THcDriftChamber::AddPlane didn't know if style was HMS, because
  style was only determined in Init.  Now fHMSStyleFlag is set in
  only one place.  Right now determined from spectrometer name, but
  could be a parameter in the future.

Fix  fStartTime=32. in THcHodoscope::Decode

Modified ReadDatabase : Added fdebugstubchisq and Corrected fhdebugflagpr to be Int
Added PrintDecode( void ) to print the drift chamber info in fHits
Modified FindSpacePoints to use the proper PlaneInd and PlanePInd
    for HMS and SOS style chambers
Changed THcDriftChamber::FindEasySpacePoint(Int_t yplane_hitind,Int_t yplanep_hitind) to
THcDriftChamber::FindEasySpacePoint_HMS(Int_t yplane_hitind,Int_t yplanep_hitind)
Added  THcDriftChamber::FindEasySpacePoint_SOS(Int_t xplane_hitind,Int_t xplanep_hitind)
commented out many fhdebugflagpr  output statements

With fdebugprintdecodeddc call Chambers[i]->PrintDecode() to output the drift chamber info after min/max time cuts
Added PrintSpacePoints()
With fdebugprintdecodeddc call PrintSpacePoints() to output drift chmaber spacepoint info

Should compare (pindex1%2), not pindex1, to determine evenness.

  Parameters are retrieved in THcHallCSpectrometer::ReadDatabase
  Geometry information saved with
     SetCentralAngles and fPointOffset.SetXYX

  THcDriftChamber
    New flag fHMSStyleChambers to determine if HMS or SOS style
    tracking should be done.  Flag is set on if the spectrometer
    name begins with 'h'.
    THcDriftChamber::LeftRight fSmallAngleApprox must be set and
    fHMSStyleChambers must be off to do SOS style.
    If not HMS style, ignore all the Yplane optimizations
  THcDC
    SOS code does "project to chamber" in link stubs.  Need to evaluate
    if this is necessary, or if HMS style should also do it.

These were related to a) scope of some variable declarations, and b) use
of pre-increment vs. post-increment of non-primitive types (this has a
slight performance hit due to the way that pre- vs. post-increment
operators are overloaded in C++.

Also cleaned up a few places where initialized variables were not being
used.

1) Need to add fNelem to DBRequest to read parameter arrays.
2) Added optional variable and set to true. Flag in the
DBRequest to tell code that parameter is optional
and does not have to be found.
3) Move setting of fNelem to before DBRequest for aero_num_pairs
 so that it can be overwritten by parameter file.

purposes.

- Add MacOSX-dependent compile options in Hall C LinkDef

  Clone some DC tests from ENGINE test files to podd
  style cuts.  Make changes to source code to support these tests.
  Correct hits in plane line in example report file.

Add fTheta_lab
Do offsets in THcHallCSpectrometer::ReadDatabase

  If ThcAnalyzer::PrintReport sees a format descriptor with 'd' at
  the end, then the value is converted to the nearest int before formatting.

    Added variables using ENGINE names
       gen_run_number
       gen_run_starting_event
       gen_event_id_number

   This is magic that allows the size of arrays to passed to
   the root tree making.

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

Re-arrange, modify and make more detailed comments in the Shower*.h header
files. Add more comments in the Shower*.cxx files.

Changed column and row numbering in THcShowerHit.h in order to get rid of
warning messages on unsigned and integer comaprisons when compiling;

Corrected a debug message in THcShower.cxx.
