F-Script 2016 refresh

[schrepfler]

With macOS, Swift3 and new XCode out, perhaps a F-Script refresher is in order?

[zmukwa]

Yes! In my opinion Swift should never have come about had F-Script caught on.Both are scripting languages but F-Script is superior and more compact and pure OOP. so yes please. Bring it on.

@schrepfler @zmukwa Anyone interested in pushing this branch forward should probably start with reviewing and merging #20.
