[boost] [iterator] Proposal to add is_const_iterator trait

Hello,

Quite often I find myself writing an is_const_iterator trait which
looks like this:

  //! A helper traits to check if an iterator is const
  template< typename ItT >
  struct is_const_iterator :
       public is_const<
            typename remove_reference<
                 typename iterator_reference< ItT >::type
            >::type
       >
  {
  };

Maybe it is worth adding to Boost.Iterators library? Or maybe there
already is something like that?
