[swift-users] Need better name, want to hide generator

[Jacob Bandes-Storch]

1. Maybe ProductGenerator?
2. Use AnyGenerator<(T, U)>?

I'd love to see something like this in stdlib:

func product<S1, S2>(s1: S1, s2: S2) ->
ProductSequence<S1.Generator.Element, S2.Generator.Element> {
    ...
}

where ProductSequence<T,U>.Generator.Element is (T, U).

So your example could be "for (x,y) in product(0..<4, 0..<2)".
