synopsis:            A natural transformation package.
description:         A natural transformation transforms a container @f a@ into another
                     container @g a@. Natural transformations act as functor morphisms
                     in category theory.
                     .
                     The naming of '~>', ':~>' and '$$' were taken,
                     with permission, from Edward Kmett's @indexed@ package.
