public interface Labeled

Interface for Objects which have a Label. For instance, they may be hand-classified with one or more tags. Note that it is for things that possess a label via composition, rather than for things that implement the Label interface. An implementor might choose to be read-only and throw an UnsupportedOperationException on the setLabel(s)() commands, but should minimally implement both commands to return Label(s).
