THcFormula::DefinedValue is removed as
     THaFormula::DefinedValue now handles the kCutScaler and kCutNCalled types

  Modify THcFormula and THcParmList to match changes to THaFormula
     (needed for reports)
  Small changes in THcInterface and detector classes for compatibility
     with new OO decoder and podd 1.6

  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).

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
