Validation #

A port of scalaz's Validation[F, S] class to dart. It's a way of codifying errors and success values in the type system. A Validation<F, S> is an interface which is implemented by either a Failure<F, S> or a Success<F, S>. Success<F, S> is a container of type S and it's meant to contain the success value while Failure<F, S> is a container of type F meant to contain the failure/error value.

Implements Functor, Applicative and Monad from concepts.
