def by[T, S](f: (T) ⇒ S)(implicit ord: Ordering[S]): Ordering[T]

Given f, a function from T into S, creates an Ordering[T] whose compare function is equivalent to:
Given f, a function from T into S, creates an Ordering[T] whose compare function is equivalent to:
```
def compare(x:T, y:T) = Ordering[S].compare(f(x), f(y))
```
This function is an analogue to Ordering.on where the Ordering[S] parameter is passed implicitly.

implicit def ordered[A](implicit arg0: (A) ⇒ Comparable[A]): Ordering[A]

This would conflict with all the nice implicit Orderings available, but thanks to the magic of prioritized implicits via subclassing we can make Ordered[A] => Ordering[A] only turn up if nothing else works.
This would conflict with all the nice implicit Orderings available, but thanks to the magic of prioritized implicits via subclassing we can make Ordered[A] => Ordering[A] only turn up if nothing else works. Since Ordered[A] extends Comparable[A] anyway, we can throw in some Java interop too.
