// ****************************************************************************
// Class: ExprGrammar
//
// Purpose:
// Implementation of a Grammar for the VisIt expression language.
//
// Programmer: Jeremy Meredith
// Creation: April 5, 2002
//
// Modifications:
// Jeremy Meredith, Wed Nov 24 11:45:56 PST 2004
// Refactored the expression-specific stuff to its own library.
//
// Brad Whitlock, Fri Oct 6 11:49:02 PDT 2006
// I made the symbols be static in the ExprGrammar class so there are no
// conflicts with Python 2.5.
//
// Jeremy Meredith, Wed Jul 23 13:29:06 EDT 2008
// Added a backslash symbol. We use it both for escaping and as
// a path separator.
