Promise vs. Bluebird for react-native

README.md

I ran this benchmark for react-native with both bluebird and promise to compare the two.

I think it's worth noting that the margin for error on this benchmark is significant. I do not attempt to claim that Promise is actually faster than Bluebird, but I do claim that the gap between them is small enough to make performance an irrelevant consideration when deciding which one to use.
