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'.

  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.

Implement 'scons cppcheck=1' functionality ... plus a few other minor updates

Generate cppcheck_report.txt in the top level directory.

Also added versioned Hall C library to .gitignore

  Remove link to engine
  Remove quick.csh script
  Undo changes to hodtest.C and hodtest_cuts.def

just for test purpose.

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.

Modified THcAerogel::ReadDatabase

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.

Update SCons compilation instructions in README.md, and improve 'scons -c' procedure.

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.
