Add variable for the difference between the Hodoscope start time
and the ADC pulse time.

Select good adc hit based on window on this difference

Have variables fGoodPosAdcTdcDiffTime and fGoodNegAdcTdcDiffTime
which are the difference
between TDC time and ADC pulse time

Replace ADC pulse time cut with cut on difference
between TDC time and ADC pulse time to select
good ADC pulse.

Eliminate cut on fStartTimeCenter in selecting good
  focal plane times.

Add code for doing the vertical target position
   correction to the optics.

Fix mistake of add target offsets twice.

Fix mistake in units for the HMS Q3 correction

Add in offsets for xptar, yptar and delta

Add in delta correction as function of xpfp and central
  momentum for HMS. This corrects for a problem in setting Q3 current.
  There was an unknown zero offset in the Q3 current.
  This was determined by T. Horn in 2003.

  To do this suppression, a trigger detector object needs to know the
  name of spectrometer it is associated with.  By default it will get
  this name from the first character of the it's own name.  This can
  be overridden with the SetSpectName method.

  Each detector object will check the global variable X.present each
  event.  If X.present is false, it indicates that the parent
  spectrometer object determineted that this spectrometer is not in
  this event, and therefor reference times are not expected.  If
  X.present is false, then the reference time warning messages will
  be suppressed.

Add ability to cut on number of PE in Cherenkov when dumping events
  for TOF calibration

Add parameter fTOFCalib_cer_lo

Add ability to cut on track beta when dumping events
  for TOF calibration

Add parameter fTOFCalib_beta_lo and fTOFCalib_beta_hi

Parameters are optional. Default set to kBig or -kBig

THere was already a possible cut on Shower energy/momentum

Moved filling of  fNRegions from parameter to before the fRegionValue array
is defined. The code had been using default fNRegions=4 regardless
of vaule  of  h_num_regions in parameter file.

Add leaf dc.chisq which is the chisquared/dof of the golden track.

Add rawnorefcorrtime to THcDCHit which is the TDC raw without
the reference time subtraction.

Add variable rawnorefcorrtdc in THcDriftChamberPlane::DefineVariables

Modify THcDriftChamberPlane::ProcessHits to call GetRawTdcHit().GetTimeRaw
  and call THcDCHit with new extra argument for raw time without reference time
  subtraction.

Modified so that the fGoodPosAdcPulseTime, fGoodNegAdcPulseTime
  or fGoodAdcPulseTime is set to kBig

Modified THcShowerRawHit::SetReference to takeADC signals

Modified THcTrigRawHit::SetReference to take ADC signals

Modified THcShowerArray::ProcessHits so that fAdcTdcOffset add to frAdcPulseTime

Modified THcShowerArray::ReadDatabase so that defaults for fAdcThreshold etc
  are before gHcParms->LoadParmValues

  This is because it is offsetting PulseTime which is double and to
  be consistent with the other detectors.

Moved writing of the TOF calibration dump file to FineProcess
Added cut on shower energy/momenutum
Add parameters fTOFCalib_shtrk_lo and fTOFCalib_shtrk_hi .

Add parameter fNumPlanesBetaCalc which allows one to set how many
planes to use in beta calculations. Useful for SHMS.
fNumPlanesBetaCalc defaults to 4 if not set.

  All Int_t variables that hold scaler values are now UInt_t
  Some variables that were Double_t are UInt_t
  Keep track of overflows so that tree variables holding scaler counts
     are correct for high rate scalers
  Catch overflows when computing differences from last scaler reading.

Fix typo in previous commit's THcCherenkov.cxx

Fix logical flaw in THcScintillator::ProcessHits in finding good adc hit in multiple hits in one channel

When looping over hits to find the best ADC hit, the code was looping over
frNegAdcPulseInt->GetEntries() or frPosAdcPulseInt->GetEntries()
which are the raw arrays that are filled for all raw hits in the plane
The code was not  using the proper indexes to access the right hits.

The logic is simpler if one loops over rawNegAdcHit.GetNPulses()
or rawPosAdcHit.GetNPulses() which are the the raw hit object for the
paritcular hit. NPulses is the number of ADC pulses that were found for that
adc channel.
The first adc pulse for the channel which is within the adc time window
then has its information saved for late insertion into the "good"
vectors for the hit if either the hit passes 'good" tdc and adc for the POS
or NEG side of the PMT.

  This will add the Hall C parameter DB (gHCParms) to the Run_Data object
  The GetHCParms method will retrieve the parameter DB

Fix mistake in THcHodoEff::End

Add back parameter hodo_gold_hits which is the number of "should" hits
  for each paddle. Needed to calculate efficiency per paddle in
