//
// *****************************************************************************
//
// CLASS DESCRIPTION (MObjectSetMessage)
//
// This class is used to register callbacks with set specific event types.
// Using the addCallback() methods, a function can be registered that will
// be executed whenever the callback specific message/event occurs.
//
// To remove a callback, use MMessage::removeCallback(). All callbacks that
// are registered by a plug-in must be removed by that plug-in when it is
// unloaded. Failure to do so will result in a fatal error.
