Clarify relationship between Functor and Applicative

In the applicative documentation, it says for an Applicative functor f: The Functor instance should satisfy fmap f x = pure f <*> x I think the documentation should be clarified that this does not need to be checked because it is a consequence of the other applicative laws. See http://hpaste.org/44315/applicative_implies_functor. -- Russell O'Connor http://r6.ca/ ``All talk about `theft,''' the general counsel of the American Graphophone Company wrote, ``is the merest claptrap, for there exists no property in ideas musical, literary or artistic, except as defined by statute.''
