  /** \class ObjectFactory
   * \brief Create instances of a class.
   *
   * ObjectFactory is a helper class used to created instances of a
   * class. Object factories are used for instantiation because they allow
   * run-time replacement of a class with a user-supplied version. For
   * example, if you wished to replace an algorithm with your own custom
   * version, or with a hardware-accelerated version, ObjectFactory
   * can be used to do this.
   *
   * This implementation of the object factory is templated and uses RTTI
   * (Run-Time Type Information) to create the name of the class it is to
   * instantiate. (The name may include template type parameters, depending
   * on the class definition.)
