   * <strong>GraduatedController</strong> is a subclass of
   * {@link adventurejs.Thing|Thing} and a base class for controllers
   * that have multiple positions which can be used to affect
   * levels of flow of
   * {@link adventurejs.SubstanceEmitter|SubstanceEmitters},
   * such as setting a sink handle which can be set to low, medium,
   * or high or any number of positions in between. This is possibly
   * overkill but that's the kind of game framework this is.
