code: public static void go(@NonNull Scene scene, @Nullable Transition transition) {
          changeScene(scene, transition);
      }
docs: Convenience method to simply change to the given scene using
  the given transition.
  <p/>
  <p>Passing in <code>null</code> for the transition parameter will
  result in the scene changing without any transition running, and is
  equivalent to calling {@link Scene#exit()} on the scene root's
  current scene, followed by {@link Scene#enter()} on the scene
  specified by the <code>scene</code> parameter.</p>
  
  @param scene      The Scene to change to
  @param transition The transition to use for this scene change. A
  value of null causes the scene change to happen with no transition.
