SConstruct

  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

Invoked with 'scons checkheaders=1'

Also added cppcheck_report.txt to .gitignore

  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

  Geometry calculations broken into separate method so
  that we don't have to read db_run.dat

Add SOS analysis to example script

  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

Untested SOS tracking code. 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'.

Invoked with 'scons checkheaders=1'

Also added cppcheck_report.txt to .gitignore

  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.
