• Add Data.Functor.Rep.Representable instances for Backwards, Reverse, and the datatypes in GHC.Generics.
• Add Data.Functor.Adjunction.Adjunction instances for some datatypes in GHC.Generics
• Add Data.Functor.Contravariant.Rep.Representable instances for U1 and (:*:) from GHC.Generics
• Add collectRep and imapRep functions to Data.Functor.Rep.
• Add MINIMAL pragmas to the Adjunction classes.
