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

1) THcDCWire.h
  a) added sigma to THcDCWire constructor which fills fSigmaWire
  b) added GetSimga method
  c) added SetSigma method

2) THcDCHit.h
 a) Added GetWireSigma method

3) THcDriftChamberPlane.h
 a) Added flag fUsingSigmaPerWire
 b) Added array fSigmaWire

4) THcDriftChamberPlane.cxx
 a) In ReadDatabase, set fUsingSigmaPerWire=0 by default
    with reading of parameter h_using_sigma_per_wire optional
    for setting fUsingSigmaPerWire.
 b) If fUsingSigmaPerWire=0 then sets all wires in array fSigmaWire to
   fSigma ( which is the simga per plane).
 c) If fUsingSigmaPerWire=1 then reads in the sigma per wire from
   a parameter file.
 d) Used new THcDCWire constructor to set the sigma for wire to fSigmaWire[nwire]
 e) Also change code so that the tzero offset is set in the  THcDCWire constructor
 f) In ProcessHits , use wire->GetTOffSet instead of the fTzeroWire array when setting
    the time.

5) THcDC.cxx
 a) In TrackFit, replace fSigma with hit->GetWireSigma()

Modify THcDCTrack::TrackFit to calculate residuals for each plane
   without the plane involved in the track.

Add tree variable residualExclPlane

Modified THcSpacePoint.h to have public member that keeps track
   of the spacepoint ID number for each chamber.
   Used in THcDC::LinkStubs

Modified THcDC.cxx and h
1) Add tree variables sp1_id and sp2_id which are the integer
    ID in the spacepoints in each chamber used in the golden track.
     The ID refers to index in array of spacepoints created in
     THcDriftChamber.cxx

2) Modify LinkStub to fill sp1_id and sp2_id for each track

3) For golden track fill sp1_ID_best and sp2_ID_best

   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.

  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 leaf dc.chisq which is the chisquared/dof of the golden track.

1) Add X,Y offsets parameter for each plane, instead of X,Y offset per chamber
2) ModifyTHcDriftChamber::CorrectHitTimes to work with SHMS chambers
3) Add GetReadoutSide method to THcDCHit class.

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

Add variables fX_fp_best,fY_fp_best,fXp_fp_best,fYp_fp_best to THcDC.h
Modified THcDC::CoarseTrack so that the variables are filled with the
quantities from the track with the smallest chi-squared.
Modified THcDC::TrackFit so that the fResidual per plane is filled with
for the track with the lowest chi-squared.
Modified THcDC::DefineVariables so that access the variables as
dc.x_fp,dc.y_fp,dc.xp_fp and dc.yp_fp

  When it was UInt_t, variable length global variables didn't get the
  length correctly and there were run time errors.

  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.

In tree they are called tnhit and trawhit.
Created two new variables for THcDriftChamber, fNthits and fN_True_RawHits.
In tree they are called tnhit and trawhit.
THcDC defined subdetector THcDriftChamber to have name Ch1 and Ch2 to do used in the tree.
THcDriftChamberPlane defined new method GetNRawhits to return fNRawhits for each plane.
Added member fNRawhits to THcDriftChamberPlane

add flags debugflagpr and debugflagstubs
add method THcDC::PrintStubs
modify THcDC::PrintSpacePoints
Set THcDC::LinkStubs() to only set fNDCTracks=0 and retrun when
  fNDCTracks>10 for HMS style chambers to match engine.

  Fix from Mark Jones with additional cleanup for
  saw's misunderstanding of space point criterion

With fdebugprintdecodeddc call Chambers[i]->PrintDecode() to output the drift chamber info after min/max time cuts
Added PrintSpacePoints()
With fdebugprintdecodeddc call PrintSpacePoints() to output drift chmaber spacepoint info

  THcDriftChamber
    New flag fHMSStyleChambers to determine if HMS or SOS style
    tracking should be done.  Flag is set on if the spectrometer
    name begins with 'h'.
    THcDriftChamber::LeftRight fSmallAngleApprox must be set and
    fHMSStyleChambers must be off to do SOS style.
    If not HMS style, ignore all the Yplane optimizations
  THcDC
    SOS code does "project to chamber" in link stubs.  Need to evaluate
    if this is necessary, or if HMS style should also do it.

  Clone some DC tests from ENGINE test files to podd
  style cuts.  Make changes to source code to support these tests.
  Correct hits in plane line in example report file.

   {prefix}dc_fix_lr
        Historically, in the ENGINE, if a hit is used in multiple
        space points/stubs, the left/right assignment for that hit, which
        is later used in track fitting, is that assigned for the last stub
        encountered with that hit.  Properly, the left right assignment
        should be allowed to be different in different space points.  If
        this parameter is set to zero (e.g. in hcana.param), then the
        ENGINE behavior is used.  For new analyses, it should be set to one.
        (Which is the default)
   {prefix}dc_fix_propcorr
        When a hit gets put into a stub, the distance of the hit from the
        discriminator can then be estimated.  In the engine, a correction to
        the drift time (and thus drift distance) is applied.  However, if
        that hit ends up in another stub, the correction will get applied again,
        resulting in a over correction.  Setting this flag to 1 will give that
        hit a different corection for each stub that it is in.

These flags will default to the new "correct" way of handling hits if
the above parameters are not set in a parameter file.  Currently, both
flags are set to zero in hcana.param to replicate the ENGINE behavior.

To implement these changes, the propagation correction and L/R information
for each hit is saved in space point and track classes.  This information
is still saved in the hit class, but only used if in ENGINE compatibility
mode.

The THcDCTrack class now saves a list of space point pointers instead
of space point indices.

The AddSpacePoint method now also copies all the hit information into
the track object so that THcDC doesn't need to explicitely copy all
the hits.

The FindStub method, which fits a stub track to a space point is passed
the space point rather than a list of hits

1.  nplusminus was not initialized corectly so small angle approximation
was never used.
2.  Change MAXTRACKS from 50 to 10 to match ENGINE.

   Add track coordinates to track structure.
   Add code for single stubs
   Try to deal with plane number/index confusion

  Uses ROOT matrix math instead of solve_four_by_four
  Nothing is done with found tracks yet.  Will need to stuff these into
     podd style tracks.  (Or a class inherited from podd style tracks.)
  Residuals not saved anywhere
  Single stub mode not yet implemented
  No printing out of trackfit results (hdebugtrackprint)

Set fDebugDC in THcDC::ReadDatabase

  Compiles and doesn't crash.
