Detailed Description

Modify zip_iterator category to be "least refined.".

7-2. Modify your zip_iterator so that its iterator category reflects the
     least-refined concept modeled by any of its underlying iterators.
     Extend the iterator implementation to satisfy all potential requirements
     of the computed category.
