App layout library

it would be nice if the Layout automagically knew to redraw

Yes, I was wondering about that. Thinking about even the clock example I feel there might be too many edge cases for us to be able to implement it easily.

Not to be contrarian, but when using a using a g.flip() approach I always have a "screen redraw" function in my code after doing some updates. The Espruino app code is generally so small that hand crafted screen updates seem like the logical thing to do -- so I'm fine with calling a "layout.update()" function.
