Add missing [fNelem] to comment for fA_Neg and fA_Neg_p declarations.

   This is magic that allows the size of arrays to passed to
   the root tree making.

Add template driven end of run reports to analyzer class

Inspired by ENGINE/CTP report generator
  Reports generated by
    THcAnalyzer::PrintReport(templatefilename,outputfilename)
    template is copied to output, {stuff} is replaced by the
       value of stuff.  Value can be formated with c formater, eg.
           {stuff:%.2f}
  ThcFormula added to allow more flexibility of variables.
    Can get number of times cuts pass or are called with:
       cutname.npassed (or cutname.scaler) and cutname.ncalled

Re-arrange, modify and make more detailed comments in the Shower*.h header
files. Add more comments in the Shower*.cxx files.

Changed column and row numbering in THcShowerHit.h in order to get rid of
warning messages on unsigned and integer comaprisons when compiling;

Corrected a debug message in THcShower.cxx.

Latest additions to Shower code

Switch submodule to analyzer (podd) release "Release-150".

   Includes addition of scons to podd.

and SCons version checking (now checks for version 4.9.9 of SCons, which
is the newly implemented version number in the local SCons installation
(in podd).  Note that this change will now require use of that updated local version as
packaged with podd.

2.  Change to SConstruct.py to add -DHALLC_MODS defines (now consistent
with Makefile) for conditional compilation in certain parts of podd.

3.  Improvement in configuration for 64bit/32bit compilation on Linux.

Use git protocol instead of https so git can be used on ifarm.

Fix compiler warning messages. Closes #3 for now.

  Use HALLC_MODS in make file to turn on Hall C changes in Podd.
  Remove unneeded and now broken includes of THaDB.h.

   {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

Conflicts:
	src/THcShower.cxx
	src/THcShower.h

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