/*
    ALWAYS include parser.h instead of y.tab.h

    Here is why:

        Since the union created by bison contains several gpl objects,
        a forward class declaration, or including the .h file must be 
        done before the union is created.

        Bison generates y.tab.h where the union is created. 
        I can't find a way to get bison to generate a y.tab.h that includes 
        forward class declarations and #include's, so I created this file.
