//  Modifications:
//    Jeremy Meredith, Wed Nov 24 12:22:32 PST 2004
//    Expression-language specific tokens are in a new,
//    more specific base class.

//    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 17:16:09 PDT 2014
//    Changed FloatConstExpr to double.
