Gets rid of vars.push_back(RVarDef ... stuff

Also do some whitespace cleanup

  This is so that hodoscope paddles in Eve are illuminated

the best track.

-Changed the name of a Good tdc variables
-Added all good adc and tdc variables
modified:   src/THcScintillatorPlane.cxx
modified:   src/THcScintillatorPlane.h

example:
-fTotNumPosAdcHits (raw hodo+ multiplicity)
-fTotNumNegAdcHits (raw hodo- multiplicity)
-fTotNumAdcHits (raw hodo multiplicity)

Indentation cleanup

   Added to THcScintillatorPlane.h
   Initialize and clear in THcScintillatorPlane.cxx
Add raw multiplicities for ADCs and TDCs

  With this commit, db_run.dat is not needed in hcana
  If THcRunParms is used, hcana will get the beam momentum from the
  parameter "gpbeam" instead of db_run.dat.  To use, use the
  THaRun::SetRunParamClass method to set the run parameter class
  to "THcRunParameters".

  THaRun* run = new THaRun(RunFileName);
  run->SetRunParamClass("THcRunParameters");

autogeneration of src/HallC_LinkDef.h - all using SCons

Accidentally deleted line

Make matched cluster variables of the array part of calorimeter private.

Initialize fY variable in the THcShowerHit::THcShowerHit default
constructor.

Correct typo in THcShowerArray::Clear, assign -1000 to fMatchClY.

Edit debug output in THcShowerArray::CoarseProcess and remove obsolete
comments THcShowerArray::MatchCluster.

Clear fSizeClustArray and fNblockHighEnergy quantitites in
THcShower::Clear, for just in case.

So files don't split.
Seems to be working, hcana has not crashed yet with file sizes
upto 2.6 GB.

Main purpose is to calculate the DC efficiency per wire
using the track information of the golden track.


THcDC.h
-----------
1) add method EfficiciencyPerWire
2) Add variables fWire_hit_did and fWire_hit_should

THcDC.cxx
------------
1) fWire_hit_did and fWire_hit_should are fixed length arrays
   the size of NPlanes that in set in method Init
2) Add variables wireHitDid and wireHitShould to the tree
3) In method SetFocalPlaneBestTrack add call to EfficiencyPerWire method
4) added EfficiencyPerWire method which loops over the hits
    and compares the wire number for the hit to the the track
    position at the plane (convert back to wire number).
    Then fills fWire_hit_did with the wire number if
    equal to the wire position of the hit equals the track.
    Also does loop over all planes and fills fWire_hit_should
    with the wire number of the track in each plane.

THcDriftChamberPlane.h and cxx
---------------------
1) Added method CalcWireFromPos

The purpose is to add a call in THcHallCSpectrometer:TrackCalc
to fill variables in THcDC for the golden track.

THcHallCSpectrometer.h
----------------------
1) Add object THcDC* fDC
2) Eliminate object fShower since it was not being used.

THcHallCSpectrometer.cxx
----------------------
1) in ReadDatabase method cast fDC in detector "dc" is defined
2) in FindVertices method add call
    to fDC->SetFocalPlaneBestTrack(hit_gold_track)
    where hit_gold_track is the HaTracks array index
    of the golden track

THcDC.h
-------
1) Add method SetFocalPlaneBestTrack

THcDC.cxx
---------
1) Eliminate filling of best focal plane quantities
   in CoarseTrack which defined "best" by lowest chi2
2) Create method SetFocalPlaneBestTrack
   a)fills the best focal plane quantities using the golden track
   b) fills fResiduals using golden track

THcShowerHit.h and THcShowerHit.cxx
---------------
1) Added fY for horizontal position
2) Added fY to THcShowerHit

THcShower.h
-----------
1) Added variables
2) Added method addY, clY to get the cluster Y position

THcShower.cxx
--------------
1) Added variables to the tree for "layer" detector
    either SHMS preshower or HMS layers
2) Added variables if the SHMS "array" is used
3) Added y position to THcShowerHit in CoarseProcess
4) In FineProcess, if SHMS "array" used then fill X,Y info
     for the Cluster and the "best" track that matched the cluster

THcShowerArray.h and THcShowerArray.cxx
---------------------------------------
1) Added methods to Get the array cluster size, X and Y position
   and block number that has the highest energy in the cluster
2) Added array fBlockClusterID for all blocks. initialized to -1
   for each block for each event and then filled with
   the cluster number if the block is included in the cluster
3) Add variable fNhits and fNgoodhits

Main purpose was to have option for per wire tzero offsets

Modified THcDriftChamberPlane.h
------------------------------
1) added fUsingTzeroPerWire as parameter flag to switch on per wire tzero offsets when parameter equals 1
2) fTzeroWire is array of tzero offsets for each wire in plane

Modified THcDriftChamberPlane.cxx
------------------------------
1) THcDriftChamberPlane::ReadDatabase
    a)set a default value of fUsingTzeroPerWire=0
    b)added to DBRequest list option to read in fUsingTzeroPerWire
    c) if fUsingTzeroPerWire=1 then separate DBRequest to read in fTzeroWire
   d) if fUsingTzeroPerWire=0 then all fTzeroWire=0

2) THcDriftChamberPlane::ProcessHits
------------------------------------
   a) Modify calcualation of drift time to subtract fTzeroWire
Double_t time = -StartTime- rawtdc*fNSperChan + fPlaneTimeZero - fTzeroWire[wireNum-1];

  Then the # tubes of the Aerogel is known.
  Remove MaxNumXXXAeroPmt constants from THcAerogel.h

The line fNpeSum += fNegNpeSum
was basically double counting the fNegNpeSum
Same for fNpeSum += fPosNpeSum
since they were in a loop over Neg and Pos hits.

Just set
fNpeSum = fNegNpeSum + fPosNpeSum
after the two loops over Neg and Pos hits

THcShowerArray
1) in ProcessHits methodfFixed mistake in index of fThresh
   was using padnum instead of padnum-1
2) add parameter pcal_arr_AdcThreshold so that threshold
   can be set by a parameter. Default is zero which gives
   the best resolution.

THcShowerPlane
1) Added the parameter cal_AdcNegThreshold and cal_AdcPosThreshold
   so that the threshold can be set through a parameter
   Previously it was hardcoded.

New parameters are added.  hallc_replay of 3/31/2017 or later is needed.

As of now, the size of the TClonesArray objects are hard-coded in the
respective header files. This is not okay in the long run. Ideally,
the size of the TClonesArrays should be defined by the parameter which
dictates how many readout detectors exist for the respective
detector. I tried doing this in the Init method however, podd
complained regarding the size of the TClonesArrays in the DEF-file
histograms. I was unsuccessful in my first attempt. This should be
addressed in the future even though things work for now.

  Process slot with clock first so that time is available to other slots
  Add option to use data in first scaler event
     (handler->SetUseFirstEvent(Bool_t)) instead of subtracting first event
     from subsequent events

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.

Main purposes:
1) Add the possibility of multiple ADC hits per channel and
   select best ADC by a time window.
2) Change ProcessHits method in ShowerPlane and ShowerArray to only
    fill "raw" TClonesArrays.
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




THcShower.h
1) Add methods GetADCMode(),GetAdcTimeWindowMin(),GetAdcTimeWindowMax()
    so that the ShowerPlane can access these parameters
2) Add parameters ADCMode,fAdcTimeWindowMin,fAdcTimeWindowMax
3) Add variables
   fNclustTrack : NUmber of cluster that matches best track
   fXclustTrack : X pos of cluster that matches best track
   fXTrack      : X pos of best track that matches cluster
   fEtrack  : Cluster energy associated with best track
   fEtrackNorm  : Cluster energy/Track momentum associated with best track
THcShower.cxx
1) Add calls to THcShowerPlane and THcShowerArray CoarseProcessHits
    in CoarseProcess
2) Moved filling of Energy in Track object to CoarseProcess
3) In FineProcess get the "best" Track object and match
   Track energy and trajectory to cluster.

THcShowerArray.h and cxx
1)add parameters fADCMode, fAdcTimeWindowMin and fAdcTimeWindowMax
2) Add method CoarseProcessHits
3) In ProcessHits fill fPosThresh and fNegThresh with a fix
    value of 250 integrated channels above pedestal.
     Need to make this a parameter.

THcShowerPlane.h and cxx
1)Gets fADCMode, fAdcTimeWindowMin and fAdcTimeWindowMax from THcShower
2) Add method CoarseProcessHits
3) In ProcessHits fill fPosThresh and fNegThresh with a fix
    value of 250 integrated channels above pedestal.
     Need to make this a parameter.

Add method
GetF250_PeakPedestalRatio() {return fPeakPedestalRatio;};

so that a detector class can calculate the pedestal that was used
in determining the pedestal subtracted FADC Pulse Integral.

This is useful if the detector class wants to set a threshold
above the pedestal.
