 * placed in the same page (e.g.: RoyalSlider, Owl Carousel or similar) without
 * interfering with the above listener.
 *
 * Solution: enable Hammer.JS custom DOM events and prevent any "swipe" gesture
 * from bubbling up to the body element by stopping event propagation via listeners
 * attached to each nested touch-enabled element (e.g.: the carousel)
