Add uncurry, left logical shift, right logical shift

It may be possible to reduce rshift further, but I'm not quite sure how because of the way quot is structured. Open to any suggestions!

Thanks! Oh yes, quot() is magical :). I'll give it a try when I have some free time. As for the new additions, should I go ahead and produce a new version or would you like to send some more stuff before the next release?

quot() is indeed magical. I had similar issues writing a gcd() function, still haven't got that quite worked out yet.

I do plan to add a few more functions, don't let that stop you if you want to push out a new release though!
