transitioner2

Introducing a wild and hacky prototype of Transitioner 2!

- "transitionProps" concept is now identical to transitioner.state
- Far simpler state management than before
- Descriptors only, no "scenes"
- No more "position"

Also, StackView is seeing improvements:
- Easier to understand when "transition props" are just this.props

- StackView only renders the current sceen and the one before it

Currently broken:
- Interpolation configuration, beyond the first push
- Attempting to move away from getSceneIndicesForInterpolationInputRange because it works with position and it is confusing as hell, but haven't worked around it yet
- Gestures, although some "backProgress" code is in the works
- Interpolation is super buggy
- onTransitionStart/End
- Header, although a lot of code is moved over

-
-## [3.10.0] - [2019-05-16](https://github.com/react-navigation/react-navigation/releases/tag/3.10.0)
-
-## Removed
-
-- `persistenceKey` no longer automatically saves and restores navigation state using AsyncStorage. Typically this would be a breaking change that would require a major version bump, but because this has always been marked as experimental in the documentation and it is unlikely to impact production apps, we are rolling it in a minor release. `persistenceKey` has been replaced with `persistNavigationState` and `loadNavigationState`. See the diff in docs: https://github.com/react-navigation/react-navigation.github.io/pull/425/files?short_path=b668b1a#diff-b668b1a4201e40b1378036dc012100fe
-
-## Changed
-
-- Removed animations from stack on web
-- Ensure that headerMode is float by default on web
-
-## Fixes
-
-- Prevent transitionConfig's useNativeDriver value being overwritten. (https://github.com/react-navigation/stack/commit/8b2af7d94209d4658abd8d799bc78744a1004b4e)
-- Update typescript with headerLeftContainerStyle and headerRightContainerStyle
-- Update typescript - Add `safeAreaInset` to `BottomTabBarProps`
-- Update typescript - `TabBarTop` is now `MaterialTopTabBar`
-- Update typescript - Remove `SwitchNavigator`, `TabNavigator` and `StackNavigator`. Added exports for `SceneView` and `SwitchRouter`
-- Update typescript - `getLabel` is now `getLabelText` in BottomTabProps and TopTabProps
-- Silence deprecated lifecycle warning in Stack Transitioner
-
-## [3.9.0] - [2019-04-23](https://github.com/react-navigation/react-navigation/releases/tag/3.9.0)
-
-## Fixes
-
-- Remove `createTabNavigator` from type definitions
-- Add missing types for `DrawerNavigatorConfig`
-- Use `preserveFocus` action param rather than matching on specific action types to determine if index needs to be updated if child router changes (https://github.com/react-navigation/react-navigation-core/pull/56)
-
-## [3.8.1] - [2019-04-12](https://github.com/react-navigation/react-navigation/releases/tag/3.8.1)
-
-## Changed
-
-- Add missing type for `enableURLHandling` to TypeScript definition (#5803)
-- Update Flow types (#5806)
-
-## [3.8.0] - [2019-04-12](https://github.com/react-navigation/react-navigation/releases/tag/3.8.0)
-
-## Fixes
-
-- `onRefresh` on exported lists `FlatList` and `SectionList` works as expected now (no need to add `refreshControl` prop explicitly)
-- On Android, the exported `ScrollView` is now same as the React Native ScrollView (but with scroll-to-top behavior added), whereas on iOS we still use react-native-gesture-handler ScrollView. We can change Android back to react-native-gesture-handler ScrollView when https://github.com/kmagiera/react-native-gesture-handler/issues/560 is resolved.
-- Look for `scrollResponderScrollTo` function in our ScrollView, in react-native 0.59 the interface appears to have changed for FlatList such that this is needed. (react-navigation-native#20)
-

 React Navigation is born from the React Native community's need for an extensible yet easy-to-use navigation solution based on Javascript.
 
 ## Installation
 
-See: https://reactnavigation.org/docs/en/getting-started.html
+Since the library is a JS-based solution, to install the latest version of react-navigation you only need to run:
+
+```bash
+yarn add react-navigation
+```
+
+or
+
+```bash
+npm install --save react-navigation
+```

 #### Is this the only library available for navigation?
 
-Certainly not! There are other libraries - which, depending on your needs, can be better or worse suited for your project. Read more in the [alternative libraries](https://reactnavigation.org/docs/alternatives.html) documentation, and read React Navigation's [pitch & anti-pitch](https://reactnavigation.org/docs/pitch.html) to understand the tradeoffs.

 # Navigation Playground Example
 
-The NavigationPlayground example app includes a variety of patterns and is used as a simple way for contributors to manually integration test changes.
+A playground for experimenting with react-navigation in a pure-JS React Native app.
 
 ## Usage
 
-```bash
-yarn # in the react-navigation root directory
-cd examples/NavigationPlayground
-yarn
-yarn start
-```
+Please see the [Contributors Guide](https://reactnavigation.org/docs/guides/contributors#Run-the-Example-App) for instructions on running these example apps.
 
-You can view this example application directly on Android phones by visiting scanning the QR code on [this site](https://exp.host/@react-navigation/NavigationPlayground) with the [Expo app](https://play.google.com/store/apps/details?id=host.exp.exponent&hl=en).
+You can view this example application directly on your phone by visiting [our expo demo](https://exp.host/@react-navigation/NavigationPlayground).
