public class Discard extends Sink implements Configurable
This actor is useful in situations where the value of an output is not needed, but for some reason, the output cannot be left unconnected. Also, when manipulating bus signals, this actor is useful if values in the middle of the bus need to be discarded. Leaving the bus unconnected in the middle will not work because no channel is allocated to an unconnected relation in a bus.

This class implements Configurable
so that the MoML filters can replace graphical actors that
implement Configurable with this actor. Note that the actors
to be replaced must have an input port named input, so
not all Configurable actors can be replaced with this actor.
