Summary: - Enables async/await in .babelrc and transformer.js - Adds regenerator to package.json. Users still need to explicitly require the regenerator runtime -- this is so that you only pay for what you use. - Update AsyncStorage examples in UIExplorer to use async/await - Update promise tests in UIExplorer to use async/await in addition to the promise API Closes https://github.com/facebook/react-native/pull/1765 Github Author: James Ide <ide@jameside.com>
