A port for controllers and refinements in modal models. This port
mirrors certain changes to it in the ports of the container of the container.
That container in turn mirrors those changes in other refinements and/or
controllers. This class is designed to work closely with ModalPort,
since changes to the ports can be initiated from either class.
