Applicative

The Applicative type-class is a Functor that also adds the capability of lifting a value in the context.

Described in Applicative Programming with Effects.

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.

To implement it in instances, inherit from ApplicativeClass.

Credit should be given where it is due. The type-class encoding has been copied from the Scado project and Scalaz 8 and the type has been extracted from Cats.
