For both the layers and the array part
  Correct calculation of coordinates of the Array modules in the
    calorimeter effciency calculations.

Previous was trying to return the reconstructed target
quantities as values which was totaly wrong.

Changed so that the references are returned. Now get the
reconstructed target quantities properly.

  fpTimes, fScinTime, fScinSigma and fScinZpos are not used.
  These arrays were given fixed size of 53.
  This commit finishes issue #53

  Add #include <set>
  Don't use new method of looping over vector

- Apparently  $?loginsh is not a good indicator of whether tcsh is
  interactive (bad Google...) so we'll look for 'setup.csh' in the
  current directory and if it is present assume it is the hcana/
  directory.
- The if($?prompt) clause should print some info text if you're
  interactive.  (Although it's not definitive either -- dammit csh.)

- The underlying problem here is that $_ is assumed to contain the path
  to the sourced file, but that isn't true for any version of tcsh I've
  tried... (I guess it must have worked for some version of tcsh?)
  Anyway, that fails and $1 is also empty in the else clause so the
  script fails.

- Reliably finding the path to a sourced file is next to impossible in
  tcsh, so just encourage/force people to pass a path to the script
  directory as an argument.

  When the db file is read, a list of crate #s and a list of
  module types is made.  The tag of each bank searched for scalers
  must have a tag that is in one of these lists.
  If all scalers are in banks tagged with the module type, then,
  SetOnlyBanks(kTRUE) should be called in which case bank tags will
  be compared only against this list of module types.

  In the end method of the Hall C rocs, the scalers are read for a final
  time and a user event 129 is created with the scaler counts.
  These events do not always appear at the end of the coda file, leading to
  the risk that triggered scaler reads will appear after the event 129s.

  If the event type of these final scaler reads is passed to the scaler
  object with the SetDelayedType(int evtype) method, then the scaler analyis
  will cache these events and analyze them at the end of the analysis.

Update podd version

  Adds support for #include directives in output definition files
  Decoders for CAEN 775 and 792 modules

This method calculates the target quantities using the focal
plane quantities and the optics matrix. Previously
this was done in THcHallCSpectrometer::FindVertices.
Now in THcHallCSpectrometer::FindVertices there is
a call to CalculateTargetQuantities


This method will be called by THcExtTarCor
to do the xtar correction.

Fixed minor bug
   FindStub was using the uncorrected drift distance
   from the hit object that was not corrected in
   CorrectHitTimes method. Need to use the corrected
   drift distance that with the spacepoint Hit structure

  So that hodtest.C keeps working

Modify THcScintillatorPlane::Clear

Change per event initialization of Good TDC quantities
from zero to kBig.

  Use pointer to event from evdata->GetRawDataBuffer() instead
  of making a local copy of the event before scanning it for
  scaler data

  There was already an AddEvtType in the base class.
  Should use SetEvtType to set the event type.  If the handler is to
  look for more than one event type, use AddEvtType for the extra
  event types.

**This class calculates kinematic variables related to the secondary (hadron)
detected particle

Fix bug introduced in THcHallCSpectrometer::FineProcess

When making changes to support THcPrimaryKine added line
track->SetEnergy
which set the track energy to energy determined from
measurement of spectrometer delta.
But this energy should be the energy measured by the
Shower calorimeter.
Deleted the line in THcHallCSpectrometer since it is not
needed anyway.

Add THcPrimaryKine and modified THcHallCSpectrometer

Add class THcPrimaryKine to calculate physics kinematics quantities for single arm

Modified  THcHallCSpectrometer so that it would fill track energy and momentum 3 vector

  An example GUI to display the periodic report during the analysis
  is included.  (rustats.tcl).  The commands to startup the GUI
  are in hodtest.C, but commented out.
