--  Provide an ordering for URIs (that is, an 'Ord' instance for
--  'URI').
--
--  This instance is provided so that URIs can be used as the
--  key of a 'Data.Map.Map'. Case is relevant for the ordering,
--  and no attempt is made to decode percent-encoded values (i.e.
--  the comparison does /not/ use a canonical or normalized form).
