  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.

       cutname.npassed (or cutname.scaler) and cutname.ncalled

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.
