//  Modifications:
//    Jeremy Meredith, Wed Nov 24 12:24:12 PST 2004
//    Renamed Engine to avt.
//
//    Jeremy Meredith, Mon Jun 13 15:46:22 PDT 2005
//    Made ConstExpr abstract and split it into multiple concrete
//    base classes.  Made FunctionExpr and MachExpr use names
//    instead of Identifier tokens.  These two changes were to
//    remove Token references from the parse tree node classes.
//
//    Kathleen Biagas, Thu May  1 17:13:28 PDT 2014
//    Changed FloatConstExpr to double.
