the best track.

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.

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 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.

  Otherwise InitHistlist doesn't have the detector map
  and can't do setup of reference time stuff or sanity checks on the
  detector mapping

Some detector classes lacked the ability to get the appropriate
Apparatus character and were only working for HMS.

    shms-calo-test directory comprises codes for testing. The 1-st
    layer of SOS calorimeter mimicks the SHMS Preshower, and positive
    side of the 2-nd layer mimicks fly's eye part.

fly's eye part.

  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

  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.

  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 is because the classes in these header files are only
  used by THcShower.

     Edit debug outputs in THcSHower and THcShowerPlane classes. Group
     outputs preferably by the end of methods, for smooth code
     flow. Structure tests of outputs for easy reading.

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.

consistent with Engine.

	   Reverse order of cycling through clusters in THcShower::MatchCluster.

    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.
