The ``Reference`` parameter will be the ``reference`` type of the

The ``Category`` parameter is the ``iterator_category`` type for the

``iterator_traits<Iterator>::iterator_category``.
The ``Access`` and ``Traversal`` parameters are passed unchanged to
the corresponding parameters of the ``iterator_adaptor`` base
class, and the ``Iterator`` parameter is passed unchanged as the
