 * root components should register themselves with
 * `AppRegistry.registerComponent`, then the native system can load the bundle
 * for the app and then actually run the app when it's ready by invoking
 * `AppRegistry.runApplication`.
 *
 * To "stop" an application when a view should be destroyed, call
 * `AppRegistry.unmountApplicationComponentAtRootTag` with the tag that was
 * pass into `runApplication`. These should always be used as a pair.
 *
 * `AppRegistry` should be `require`d early in the `require` sequence to make
 * sure the JS execution environment is setup before other modules are
 * `require`d.
