 * $.with(myView).animate(new QuickMap(QuickEntry.qe("alpha", .8f), QuickEntry.qe("width", 50%)), new AnimationOptions());

 * @param properties mapping of property names and final values to animate
 * @param options the options for setting the duration, easing, etc of the animation
 * @return this
