Fallback

When Rabbits can not find a page that matches the given url, a fallback is necessary. You can register a FallbackNavigator when initialize Rabbits like this.

registerFallbackNavigator(new Navigator() {
  @Override
  public RabbitResult perform(Action action) {
    //
  }
});

You may want to navigate to a web browser to load target url or tell user the url is broken, it’s up to you. All the information about current navigation can be found in the Action instance.
