Summary: @public
Make the flow type of TimingAnimationConfig and TimingAnimation the same as SpringAnimationConfig and SpringAnimation.
This is a more accurate flow type as both are multiplexed through maybeVectorAnim().

Summary:
1) Makes params more intuitive (only one now, bounciness, which maps intuitively to number of oscillations).
2) Satisfies boundary conditions (f(0) = 0, f(1) = 1) so animation actually goes where you tell it (before it would finish at a random location depending on the input params).
3) Simple test to verify boundary conditions.
