``function_output_iterator`` requirements
.........................................

``UnaryFunction`` must be Assignable and Copy Constructible.  



``function_output_iterator`` models
...................................

``function_output_iterator`` is a model of the Writable and
Incrementable Iterator concepts.



``function_output_iterator`` operations
.......................................

``explicit function_output_iterator(const UnaryFunction& f = UnaryFunction());``

:Effects: Constructs an instance of ``function_output_iterator`` 
  with ``m_f`` constructed from ``f``.


``operator*();``

:Returns: An object ``r`` of unspecified type such that ``r = t``
  is equivalent to ``m_f(t)`` for all ``t``.
  

``function_output_iterator& operator++();``

:Returns: ``*this``


``function_output_iterator& operator++(int);``

:Returns: ``*this``
