Storage class getCount and clear implementation
[events] Refactored GestureHandler. It features a simpler interface, dispatches its custom events to target DOM elements and attaches *only one* event handler for each touch event. It's great.
[events] GestureHandler's touchend event handler is smarter about possible taps with no touchmoves.
[events] GestureHandler accepts an optional root element that would be useful for iframes.
[gestureHandler] For tap event, max distance between touchstart and touchend increased to 20px. Tap handler is more accurate.
