+The tap module provides a gesture events, "tap", which normalizes user interactions
+across touch and mouse or pointer based input devices. This can be used by application developers
+to build input device agnostic components which behave the same in response to either touch or mouse based
+interaction.
+
+'tap' is like a touchscreen 'click', only it requires much less finger-down time since it listens to touch events,
+but reverts to mouse events if touch is not supported.

+@example
+
+ YUI().use('event-tap', function (Y) {
+ Y.one('#my-button').on('tap', function (e) {
