/*!
    The container node in Maya bundles together a group of related nodes.
	The user can then publish attribute names to the container, and bind
	attributes from nodes in the container to the published names.

	MContainerMessage class allows the API user to register callbacks that
	inform them about changes to published attributes on containers.

    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.
