/** \brief Abstract ring base class.
\ingroup ring
* Found in the file \sa{linbox/ring/abstract.h}.
* Abstract base class used to implement the ring archetype to minimize
* code bloat. All public member functions of this class are purely
* virtual and must be implemented by all derived classes.
*
* If a template is instantiated on the ring archetype, we can change the
* ring it is using by changing the derived class of this class. This allows
* us to change the ring used in a template without having to reinstantiate
* it. This minimizes code bloat, but it also introduces indirection through
* the use of pointers and virtual functions which is inefficient.
