This CL adds license blocks and cleans up a number of Dart idioms in fn.
Specifically, I've marked several fields as |final| and used Map#putIfAbsent in
some appropriate places.

If there is jank, we might not get a frame time that's just after the last
frame, which means we'll stop generating animation frames before hitting 1.0
exactly.
In this CL, we introduce state to takeWhile to cancel the stream after emitting the
1.0.

This is just a proof of concept. If we like this direction, it will move out of the examples directory (likely re-written) and be committed in smaller pieces with unit tests and formal reviews.
