This is a module for legacy "CustomComponents" to gracefully deprecate.
The navigator component in this module will behave identically as the one in old version of React native, with one exception:
Latest documentation is available here: https://facebook.github.io/react-native/docs/0.43/navigator.html
- Navigator.props.sceneStyle must be a plain object, not a stylesheet!
(this breaking change is needed to avoid calling React Native's private APIs)
