Update configuration script for MacOSX (Mavericks)

Also added versioned Hall C library to .gitignore
Fixed configuration issue  that caused segmentation fault on MacOSX
Implement 'scons cppcheck=1'

Generate cppcheck_report.txt in the top level directory.
Merge pull request #34 from brash99/develop_macosx

Implement 'scons cppcheck=1' functionality ... plus a few other minor updates
Untested SOS tracking code.
  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.
Added ability to check required C header files to configure section

Invoked with 'scons checkheaders=1'

Also added cppcheck_report.txt to .gitignore
Merge pull request #35 from sawjlab/sostracking

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'.
Small Drift chamber code fixes so it won't crash with with SOS data.
As SOS hodoscope doesn't use stofusinginvadc, make it optional.
Make Xcal_fv_test an optional parameter SOS compatibility.
Changes to control files to analyze SOS data.
  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
Merge pull request #36 from sawjlab/sostracking

Add SOS analysis to example script
Merge remote-tracking branch 'upstream/develop' into develop_macosx
Update to latest Release-150
  Geometry calculations broken into separate method so
  that we don't have to read db_run.dat
Get spectrometer angle and momentum for Hall C style parameters
  Parameters are retrieved in THcHallCSpectrometer::ReadDatabase
  Geometry information saved with
     SetCentralAngles and fPointOffset.SetXYX
Fix bug in SOS small angle LR approx

Should compare (pindex1%2), not pindex1, to determine evenness.
Add some SOS DC histograms and scripts
Added fdebugprintrawdc to output the raw drift chamber info
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
Modified AddPlane for SOS and HMS style chambers
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
In THcHodoscope::ReadDatabase make reading in fTofTolerance optional and set default = 3.0
Fix  fStartTime=32. in THcHodoscope::Decode
