First hit above this cut is taken as the reference time.
   Cuts are per detector and read as an optional parameter in
   each detector class.  TDCs and Flash ADC times have separate cuts.

Implement a second method of selecting best reference time.
  If InitHitList is passed a possitive reference time cut,
    use the first reference time above that cut.  If none of the
    hits pass the cut, then no reference time is set
  If InitHitList is passed a negative cut, the cut is taken to be
    the absolute value of the cut, but a reference time is garuanteed
    to be set as long as there is at least one reference time hit.
    If none of the reference time hits pass the cut, then the last
    hit is taken to be the reference time.  (Should be the largest.)

Allow reference time cuts for all the spectrometer detector classes
  Hodoscopes, drift chambers, Aerogels, Gas Cherenkovs, Calorimeters

  Add End method to each detector that calls MissReport which
  prints the number of events with missing TDC and ADC reference times.

  in THcDummySpectrometer and THcTrigApp
  by removing calls to DefineVarsFromList that are not needed because
  those classes define no variables.

THcHallCSpectrometer
  1) Add variables fMispointing_x and fMispointing_y
    which are filled by parameters hmispointing_x, hmispointing_y
      in PARAM/HMS/GEN/hmsflags.param and pmispointing_x, pmispointing_y
      in PARAM/SHMS/GEN/shmsflags.param .
   The offsets are used in THcExtTarCor and THaReactionPoint
  2) Modify argument to method CalculateTargetQuantities to be xtar
     instead of gbeam_y .

THcExtTarCor
   1) add call to get spectrometer pointing offsets
   2) The mispointing_x is added to xtar
   3) Set xtar to start as -beam_y = - vertex(1)+mispointing_x for first call to CalculateTargetQuantities
      After first call the xtar is recalculated using the returned xptar
      and a second call is done to get the target xptar,ytar,yptar and delta.
    4) Fill golden track with final xtar

Added call trkifo->Set since it is used in THcPrimaryKine and THcSecondaryKine

Fill golden track with target quantities after correction for
  vertical target position.

When filling beam position that is used in determining the reaction
  point multiply the raster X by -1 to put in the right handed coordinate system

The raster coordinate system is left-handed to match the EPICS beam
  coordinate system.

Increase default size
    static const int fMaxAdcChannels = 200;
    static const int fMaxTdcChannels = 200;

Add TH1f histogram hTime to replace timehist array

1) add error message if Time between sucessive reads is zero.
    This should never happen.

2) Add the event number of that scaler read to the Scaler root tree
   The tree variable is evNumber

Added a check that fDeltatime>0 when calculating
charge and current.

   For a TrigDet associated with one spectrometer, call SetSpectName
   so that H.present or P.present can be found.
   For coin TrigDet, supply a list of event types for which warnings
   should be suppressed.

  Other missing energy def name changed to emiss_nuc
  Get secondary particle mass from the parameter DB
    instead of the spectrometer object

Switched X and Y rasters to make them consistent with epics left-handed coordinate system, and changed sign of x in fDirection() to make the beam position a right-handed system

  Don't use prefix to construct name

  It was a stupid idea

Edited CalculatePedestals() method to correctly fill rasters, and corrected typos in fYA_ADC and fXB_ADC when calculating the currents

  The Event handler can now be given any name.
    (Only one THcConfigEvtHandler should be instatiated.)
  Also:
     THcConfigEventHandler clears CrateInfoMap on Init.
     THcHitList caches FADC config on first event

Add _ti_ps_factors[] array with prescale factors computed from exponents

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.
