- 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.

More logging.

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

  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.

the best track.

3) Add CoarseProcessHits method to ShowerPlane and ShowerArray
    to fill the "good" data arrays from call in THcShower:CoarseProcess
4) Moved code to fill Track object with energy from FineProcess
   to CoarseProcess so that the Track->Get(Energy) can be used by other
    detectors in their FineProcess.
5) FineProcess loops over Track object add gets Track energy
6) Add AdcErrorFlag TClonesArray to be filled to check for
   problems with FADC

       This is to match the class name defined in those files
       Also add THcShowerHit to the Makefile

THcShowerHitClass.h file.

from SHMS shower counter. Make THcShowerArray a friend class to
THcShower in order to have access to the debug flags.

  Added as an optional sub detector THcShowerArray to the THcShower class
  Get hit data with GetData method instead of hit member variables
    so as to be compatible with FADC compatible hit list

negative side PMT signals from the HMS and SOS calorimeters.

    Changes in the Ycor method of the THcShower class, and in
    examples/PARAM/hcana.param input file.

  Clean up THcShower.h and THcShower.cxx.
  typedef vector<THcShowerHit*> THcShowerHitList by
  typedef set<THcShowerHit*> THcShowerHitList.
  Remove inheritance of class THcShowerCluster from THcShowerHitList.
  Define THcShowerCluster as THcShowerHitList, aka set<THcShowerHit*>.
  Remove inheritance of class THcShowerClusterList from
        THcShClusterList, a.k.a. vector<THcShowerCluster*> container.
  Define THcShowerClusterList as vector<THcShowerCluster*>.
  Rename THcShowerHitSet by THcShowerHitList.
  Rename HitList (related to the HMS calorimeter) to HitSet.
  Add operator< in THcShowerHit class, in order to have THcShowerHitSet
    objects to be properly sorted.

    Add variable fEtot= the total energy of the calorimeter which
      is calculated in Decode method
    Add variable fEtotnorm= the total energy of the calorimeter
      divided by central spectrometer which is calculated in Decode method
    Add both to DefineVariables list as etot and etotnorm

       State neighbours hits in a row separated by single block in
       THcShower::IsNeighbour method. This allows for inclusion of a
       stand alone hit of low energy deposition (presumably coming
       from noise in a channel) into a big cluster, hence reducing
       differences between engine and hcana.

  For the most part this is making sure that the loop variable in
  a for loop is of the same type as the variable that it is compared
  against (Often a UInt_t).

This reverts commit e9ce1040.

first track from the HMS shower counter code.

    Remove variables and code related to the maximum cluster of hits,
    and association of a cluster to the 1-st spectrometer track in
    THcShower.h and THcShower.cxx. Those were used for testing of the
    code, not needed any more.

    Add fdbg_raw_cal flag in THcShower.h.
    Initiate fdbg_raw_cal with engine's hdbg_raw_cal in THcShower::ReadDataBase.
    Supply calorimeter debug flags to otherwise free print-outs in the
    THcShower and THcShowerPlane methods.

    Add fdbg_init_cal flag in THcShower.h.
    Initialize fdbg_init_cal from engine's hdebugflaggeometry
    in THcShower::ReadDataBase.

Goldent track is moved to THcHallCSpectrometer::TrackCalc()
  if  fSelUsingScin == 0 then golden track is calculated just
  like podd. i.e. it is the first track with minimum chi2/ndf
  with sorting ON

  if fSelUsingScin == 1 then golden track is calculetd just like
  engine/HTRACKING/h_select_best_track_using_scin.h. This method
  gives the best track with minimum value of chi2/ndf but with
  additional cuts on the tracks. These cuts are on dedx, beta
  and on energy.

  This commit also corrects and modifies the beta code written
  in the THcHodoscope::FineProcess

  At this point we have godlend track and in additoion to
  previous vlues the following values are set to a track:
  Energy, beta, chi2 of beta and dedx[track][first hit].

NOTE: For some tracks we have large differences in value of chi
      square between ENGINE and hcana and this is already
      discussed in the last group meeting. Following emails are
      exchanged regarding this difference of chisquare.

email to Mark:

Hi Mark,
I tried to trace the origin of difference of the chi square value between
ENGINE and hcana. Please see the attached file, it has long table which I
cannot present in this email. Or you can see the file at the following
link, thanks.

Mark's reply:
Ahmed,
        Thanks. I agree with what you see, but there is also another reason
for the difference. For the space point in ch2 the engine and hcana
choose different left/right combinations. That is why you see the large
jump in the summed chi2 from planes 9 and 10. The two codes pick
different left/right because there is a cut on the difference between the
measured stub xp and an expected xp = sp->GetX()/875  and one code has a combination
slightly below the cut value and the other slightly above. I do not see a way
to make the codes agree more exactly since the stub fitting involves a matrix
inversion.

                Cheers,
                       Mark

calorimeter.

Add list of clusters fClusterList in THcShower class.
Add method THcShower::GetShEnergy(THaTrack*).
Add method THcShowerClusterList::clear() in THcShowerCluster.h.

Remove track related variables from the HMS Shower class, use ntuples
from the track (H.tr) block instead in the HMS calorimeter calibration
scripts.

- Remove a block of duplicated track related variables from the
THcShower class which have been added for calorimeter calibration
purposes.

- In hcal_calib directory, replace those variables with correspondent
variables from H.tr block in the calorimeter calibration class
(THcShowerCalib.h), in the cut (hcal_replay_cuts.def) and output
(output_hcal_replay.def) definitions.
