/**

 * 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>.
