        Module Name: Events.h
        Module Date: 05/23/2004
        Module Auth: John Orlando
        
        Description: This file provides the external interface
        to the events that can be published/processed in the
        system.  It is specifically by itself (and nothing
        else should be defined in here) so that both .c and
        .S (assembly) files can include this file without
        a problem.
