Lens-Simple makes it easier to use the combinators from the original van Laarhoven-O'Connor lens library: Russell O'Connor's lens-family package. For various reasons, O'Connor's package has a rather complicated structure; our purpose here is to ignore all this. The zoom preferred here is from Lens.Family.State.Strict. makeLenses and makeTraversals & co are re-exported from Dan Burton's lens-family-th.
