trait Comonad[F[_]] extends Serializable with Type[F]

The Comonad type-class is the dual of Monad. Whereas Monads allow for the composition of effectful functions, Comonads allow for composition of functions that extract the value from their context.

To implement Comonad:

The purpose of this type-class is to support the data-types in the Monix library and it is considered a shim for a lawful type-class to be supplied by libraries such as Cats or Scalaz or equivalent.

CREDITS: The type-class encoding has been inspired by the Scato project by Aloïs Cochard and Scalaz 8 and the type has been extracted from Cats.
