   * The %Factory class provides a single location for instantiating
   * various strategies based on parameter list choices.  It provides a
   * create() method for each type of strategy which instantiates strategy
   * objects for that type.  Each create method takes as arguments a
   * ref-count pointer to a LOCA::Parameter::SublistParser and a parameter
   * list.  The parameter list determines which strategy to choose and also
   * should provide any parameters the strategy requires.  The sublist parser
   * provides a parsed version of the top-level parameter list and allows
   * strategies to easily obtain other sublists from the top-level list.
   * A user-supplied factory may also be provided for instantiating
   * user-defined strategies.  If a user-defined factory is supplied,
   * each create method will first attempt to instantiate the strategy using
   * it, and then instantiate strategies itself if necessary.
