        This function is used to find an access vector that matches
        a 'required' access. To do this we comput a signed numeric
        value that indicates how close the req access is to the
        'provided' access vector. The closer the value is to 0
        the closer the match, with 0 being an exact match.

        A value over 0 indicates that the prov access vector provides more
        access than the req (in practice, this means that the source type,
        target type, and object class is the same and the perms in prov is
        a superset of those in req.

        A value under 0 indicates that the prov access less - or unrelated
        - access to the req access. A different type or object class will
        result in a very low value.

        The values other than 0 should only be interpreted relative to
        one another - they have no exact meaning and are likely to
        change.

        Params:
          req - [AccessVector] The access that is required. This is the
                access being matched.
          prov - [AccessVector] The access provided. This is the potential
                 match that is being evaluated for req.
        Returns:
          0   : Exact match between the acess vectors.

          < 0 : The prov av does not provide all of the access in req.
                A smaller value indicates that the access is further.

          > 0 : The prov av provides more access than req. The larger
                the value the more access over req.
