/**
 * Outside events are synthetic DOM events that fire when a corresponding native
 * or synthetic DOM event occurs outside a bound element.
 *
 * The following outside events are pre-defined by this module:
 * <ul>
 *   <li>blur</li>
 *   <li>change</li>
 *   <li>click</li>
 *   <li>dblclick</li>
 *   <li>focus</li>
 *   <li>keydown</li>
 *   <li>keypress</li>
 *   <li>keyup</li>
 *   <li>mousedown</li>
 *   <li>mousemove</li>
 *   <li>mouseout</li>
 *   <li>mouseover</li>
 *   <li>mouseup</li>
 *   <li>select</li>
 *   <li>submit</li>
 * </ul>
 *
 * Define new outside events with
 * <code>Y.Event.defineOutside(eventType);</code>.
 * By default, the created synthetic event name will be the name of the event
 * with "outside" appended (e.g. "click" becomes "clickoutside"). If you want
 * a different name for the created Event, pass it as a second argument like so:
 * <code>Y.Event.defineOutside(eventType, "yonderclick")</code>.
 *
 * This module was contributed by Brett Stimmerman, promoted from his
 * gallery-outside-events module at
