 * Geometry functions which
 * augment the existing methods on {@link Geometry},
 * for use in XML Test files.
 * This is the default used in the TestRunner, 
 * and thus all the operations 
 * in this class should be named differently to the Geometry methods
 * (otherwise they will shadow the real Geometry methods).
 * <p>
 * If replacing a Geometry method is desired, this
 * can be done via the -geomfunc argument to the TestRunner.
