Infix notation for everything

Consider leveraging simulacrum. It would make the api much less awkward.

Compare
```scala
AndXorK2[List, Int, String].transformP(new (List ~> Option) { def apply[A](l: List[A]) = l.headOption })((List(1), List("a")))
```
to
```scala
(List(1), List("a")).transform(new (List ~> Option) { def apply[A](l: List[A]) = l.headOption })
```
