 synopsis:            Opaleye wrapped up in classy MTL attire.
 description:         
     Classy MTL extension of the lovely Opaleye library, which simply just wraps things up in a MonadReader , MonadError context where the config & error are constrained by Classy Lenses & Prisms rather than by concrete types
