 *
 * jGrowl is a jQuery plugin implementing unobtrusive userland notifications.  These 
 * notifications function similarly to the Growl Framework available for
 * Mac OS X (http://growl.info).
 *
 * Changes in 1.0.2
 * - All CSS styling is now external.
 * - Added a theme parameter which specifies a secondary class for styling, such
 *   that notifications can be customized in appearance on a per message basis.
 * - Notification life span is now customizable on a per message basis.
 * - Added the ability to disable the global closer, enabled by default.
 * - Added callbacks for when a notification is opened or closed.
 * - Added callback for the global closer.
 * - Customizable animation speed.
 * - jGrowl now set itself up and tears itself down.
 *
 * Changes in 1.0.1:
 * - Removed dependency on metadata plugin in favor of .data()
 * - Namespaced all events
 *
 * @todo    Group by header.
