public class SimpleConstituent
extends Constituent

A SimpleConstituent object defines a generic edge in a graph. The SimpleConstituent records only the endpoints of the Constituent, as two integers. It doesn't label the edges. (It doesn't implement equals() since this actually decreases performance on a non-final class (requires dynamic resolution of which to call).)
