//
// CLASS DESCRIPTION (MNodeMessage)
//
// This class is used to register callbacks for dependency node messages
// of specific dependency nodes.
//
// There are 4 add callback methods which will add callbacks for the
// following messages
// Attribute Changed
// Attribute Added or Removed
// Node Dirty
// Name Changed
//
// The first parameter passed to each of the add callback methods is the
// depenency node that will trigger the callback.
//
// Callbacks that are registered for attribute changed/addedOrRemoved messages
// will be passed an AttributeMessage value as a parameter. This value
// indicates the type of attribute message that has occurred. See the
// enum for all available messages.
//
// Each method returns an id which is used to remove the callback.
//
// 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.
