/** \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.)
*
