 ##### Methods
-- __apply(rollbackTimeout: Number = 0, restartImmediately: Boolean = true): Promise<void>__: Applies this package to the application by unzipping its contents (e.g. the JS bundle) and saving it to the location on disk where the runtime expects to find the latest version of the app. If the restartImmediately parameter is set to false, the apply will complete, but it won't take effect until the next time that the app is restarted. Otherwise, the app will be immediately restarted after performing the apply, so that the end-user sees the changes.
