 * An implementation of the Allen interval variable.  This implementation is
 * different from {@link AllenInterval}, which is a {@link MultiVariable} representing
 * an interval as two timepoints.  This implementation is used for qualitative temporal
 * reasoning (e.g., with the {@link FuzzyAllenIntervalNetworkSolver}), whereas the {@link AllenInterval}
 * is used for quantitative temporal reasoning (e.g., by the {@link AllenIntervalNetworkSolver}).
