/**
 * Problem: an Hammer.JS instance listens to the horizontal swipe gestures
 * targeted at a top-level html element (e.g.: body) in order to show/hide
 * an off-canvas menu; it should be possible to browse a touch-enabled carousel
 * 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)
