 * Adds the special Class "Thing", owl:Thing.
 * <p/>
 * NOTE. Yes you could call this function with a name unlike "Thing" or a different URI as
 * {@link TransformOWLtoGraph#OWL_THING_CLASS_URI} because a user can define an "own" class with the namespace of
 * OWLThing. In this case the class should be shown as a OWLThing class.
 * There are also several cases where user doesn't define the target or the source of a property. In this case the
 * target / source of this property should be an OWLThing class. It should be possible for the GraphDataModifier to
 * add an OWLClass with different or without an OWLClassThing Namespace (this may not be through for
 * TransformOWLToGraph).
 *
 * @param instances  the count of instances
 * @param classID    the id of this class
 * @param name       the name of this class
