New required Cerenkov and Aerogel parameters in hcana.def
  cuts and output.def updates
  remove now unsupported mirror efficiencies from report.template

  to account for changes to Cerenkov class

  Fix fptime formulae in output.def
  Remove unused parameter from THcHodoEff
  Remove undefined parameter from report.def

  Variable found in a report template is first tested to see if it is a
  Hall C style parameter (in gHcParms).  If not, then tested to see if it
  is a global variable (in gHaVars).

  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.

  If ThcAnalyzer::PrintReport sees a format descriptor with 'd' at
  the end, then the value is converted to the nearest int before formatting.

    Added variables using ENGINE names
       gen_run_number
       gen_run_starting_event
       gen_event_id_number

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
