A Constituent object defines a generic edge in a graph. The Constituent class is designed to be extended. It implements the Comparable interface in order to allow graphs to be topologically sorted by the ordinary Collection library in java.util, keying primarily on right-hand node ID number. The Constituent class implements most of the functionality of the the Label interface by passing all requests down to the Label which might be contained in the Constituent. This allows one to put a Constituent anywhere that a Label is required. A Constituent is always Scored. @author Christopher Manning
