- Each detector should override ManualInitTree(TTree*)
- This method should be used to add branches to the tree
- These branches should be data members of the detector.

- removed spdlog ( now in analyzer)
- added logging to THaAnalzyer (podd)

fGoodFlags holds event-by-event data, but was never cleared,
eventually growing to several hundred megabytes in a long analysis.
The effciency calculations in THcHodoEff that rely on the contents
of fGoodFlags have been most certainly garbage up to now.

I've replaced the event-by-event ClearEvent() method with the
standard virtual function Clear() and have added fGoodFlags.clear()
there.

Also, I've added assertions to the hodoscope code to check
the validity of some non-obvious array indices. Nothing triggers;
the index logic appears sound (despite its appearance ...)

- Mixins defined in Logger.h
- Mixin used in base classes (THcDC is currently a good example)

Added a few more spdlog loggers

Added logging to many.

- Added logging to hodoscope, aerogel hitlist and detectormap
- Working on scandalizer features.

Add tree variables TimeHist_Sigma, TimeHist_Peak and TimeHist_Hits
for the peak,sigma and number of hits of the histogram
 of PMT times used in EstimateFocalPlaneTime

Modified Hodoscope and ScintillatorPlane  classes for new time calibration method.

Add AdcTimeWindowMin and Max for each pmt

Add tree variables GoodPosAdcMult and fGoodPosAdcHitUsed

Moved the old track efficiency tests to OriginalTrackEffTest method and
this is presently commented out. Eventually can be eliminated.

The old track efficiency assumed that both planes had matching
  paddlle spacing which is not true for SHMS.

Added new method TrackEffTest which calculates the number of clusters
  in each plane and the position for the cluster for scintillator
  paddle that had good times in both ends. Selects events with
  one cluster with size of 1 or 2 in either 4 of 4 planes
  or 3 of 4 planes. Also checks that the events are inside
  a given range of scintillator paddles.

   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.

Add TH1f histogram hTime to replace timehist array

  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

  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.

-Added fAdcTimeWindow Min/Max to THcHodoscope.cxx (.h)
-Added fAdcTimeWindow Min/Max to THcScintillatorPlane.cxx (.h)
-Initialized loop over number of hits inside the FillDynamic_Pedestal() method
-added some variables in the THcScintillatorPlane.cxx Dynamic Pedestal Method
-Added loop over adc_pos and adc_neg hits, and required the hits to fall
within fAdcTimeWindow Min/Max
-Added the requirement of at least a valid (adc && tdc) on either end of a bar
-re-defined boolean operator for adc_pos/adc_neg to be True if  they passed the errorflag and timeCUT requirements in the fADC_Dynamic Pedestal method.
-- deleted adc_pos/neg initial definitions, and set their initial values to -999.

The change was in part of code which calculates the fiducial
 area of the scintillators where the drift chamber should
 have had a track. This sets fGoodScintHits=1 or 0
 Used to calculate the DC track efficiency

1) Eliminate variables fScinShould and fScindid. These will
   be defined in the cuts file.
2) Eliminate code which determined bestXpScin and bestYpScin since
   since these variables were never used.
3) Initialized  fHitSweet1X,fHitSweet1Y,fHitSweet2X and
   fHitSweet2Y to zero.
4) Change so that loops over number of paddles do not
    assume that X (Y) planes for Ch1 and Ch2 have same number
    of paddles.

The change was made so that NonTrackingDetector could have information
on the "best" track in their FineProcess method.

In THcHallCSpectrometer::FindVertices the "best" track will be selected
and the Track object will its SetIndex method to set the index to 0 for
the best track. The other track will have index=1 or greater.

In the NonTrackingDetector FineProcess, the track that is selected to
be the "best" can be found by looping through the tracks checking
track index using Track.GetIndex() for find the track with Index=0.

In  the NonTrackingDetector's CoarseProcess they need to set quantities
for the Track object needed for selection of "best" track for the
"prune" and "usingscin" track selection methods.

1) In THcHallCSpectrometer:
  a) Moved selection methods of "best" track from TrackCalc to FindVertices.
  b) Removed setting of Golden Track in the selection methods.
  c) Add setting of Track Index=0 for "best" track in each selection method.
  d) Modified TrackCalc method to loop through Track object and find
     the track with Index=0 and set the Golden Track equal to this Track.

2) In THcHodoscope.cxx
  a) Moved all calculations in FineProcess into CoarseProcess
  b) CoarseProcess calculates the scintillator Beta for each Track
     and does Track->SetBeta.
  c) In determination "zcor" for corrected hits times
      use fBetaNominal instead fBetap from track. Still use Track
      to get distance.
  c) Eliminate fBetap variable which was using the Track momentum
  d) Add variable fBeta which is just from scintillator times.
  e) In FineProcess fill fBeta with the the beta associated
     with the "best" track determined by selecting Track with index=0

Temporarily set THcHodoscope.cxx so that only the first three planes are used to calculate the focal
plane time and beta.
In THcHodoscope , Modified format for writing out the dump file used in hodo calibration.
Add cosmicflag to THcScintillatorPLane so the corrected time is done right for cosmics.
Modified hc_hodo_calib/tofcal.f so that it uses detector 10 as the reference
and that it writes out better defualts for parameters in there are not enough events for a PMT.

fScinHitPaddle is a std::vector<std::vector<Double_t>>. It was
cleared and rebuilt for each event with the same structure,
instead of just zeroing out all the values.

Now it is created in only one place, and than zeroed instead of
cleared.

Changed data type in fScinHitPaddle from Double_t to Int_t. Should
be changed to bool, but then all logic should be changed.

The fCosmicFlag is used in EstimateFocalPlaneTime
The start time for the drift chamber is determined as an average
of the focal plane times for each hodo plane. Need to account for
the TOF from the hodoscope to the focal plane (z=0). For cosmic
data need to add this TOF to the corrected scintillator time, while
usually one needs to subtract this TOF. Add a flag as parameter to
switch between these modes.

Modify default tdc_neg and tdc_pos = -999
SetCorrectedTimes when only oneside has TDC within in window

   in THcHodoscope::FineProcess

Lot's of changes to
 THcScintillator::ProcessHits
 THcHodoscope::EstimateFocalPlaneTimes
 THcHodoscope::FineProcess

  THcRawHodoHit gives reference time corrected TDC values
  THcScintillator plane adds a per plane offset to the raw tdc value
  First positive TDC value after adding offset is used

  Method for number of planes
  Method for list of plane objects
  Method to return "good" flags for given track, plane and counter

  These are left over from early development when there wasn't a table
  drive way to retrieve parameters.
  (Now we use gHcParms->LoadParmValues())

  in calculation of drift chamber start time

   Don't repeat comparisons of tdc values
   with fScinTdcMin and fScinTdcMax because hits only get added to
   fHodoHits (and previously fPosTDCHits, fNegTDCHits, ...) if
   the times are within these ranges.
  In THcHodoscop, remove members of fTOFPInfo that are just used
   locally.

section of THcHallCSpectrometer to be clearer.
Does not follow the fortran in detail, but should be doing the same
thing.
