Usage
-----
The user of ``iterator_facade`` derives his iterator class from an
specialization of ``iterator_facade`` which takes the derived iterator
class as the first template parameter. The order of the other
template parameters to ``iterator_facade`` have been carefully chosen
to take advantage of useful defaults. For example, when defining a
constant lvalue iterator, the user can pass a const-qualified version
of the iterator's ``value_type`` as ``iterator_facade``\ 's ``Value``
parameter and omit the ``Reference`` parameter which follows.

The derived iterator class must define member functions implementing
the iterator's core behaviors. The following table describes
