   * criteria defining the event are met, call notifier.fire( [args] ); to
   * execute event subscribers.</p>
   *
   * <p>The first parameter is the name of the event.  The second parameter is a
   * configuration object which define the behavior of the event system when the
   * new event is subscribed to or detached from.  The methods that should be
   * defined in this configuration object are <code>on</code>,
   * <code>detach</code>, <code>delegate</code>, and <code>detachDelegate</code>.
   * You are free to define any other methods or properties needed to define your
   * event.  Be aware, however, that since the object is used to subclass
   * SyntheticEvent, you should avoid method names used by SyntheticEvent unless
   * your intention is to override the default behavior.</p>
   *
   * <p>This is a list of properties and methods that you can or should specify
   * in the configuration object:</p>
   *
   * <dl>
   *   <dt><code>on</code></dt>
   *       <dd><code>function (node, subscription, notifier)</code> The
   *       implementation logic for subscription.  Any special setup you need to
   *       do to create the environment for the event being fired--E.g. native
   *       DOM event subscriptions.  Store subscription related objects and
   *       state on the <code>subscription</code> object.  When the
   *       criteria have been met to fire the synthetic event, call
   *       <code>notifier.fire(e)</code>.  See Notifier's <code>fire()</code>
   *       method for details about what to pass as parameters.</dd>
   *
   *   <dt><code>detach</code></dt>
   *       <dd><code>function (node, subscription, notifier)</code> The
   *       implementation logic for cleaning up a detached subscription. E.g.
   *       detach any DOM subscriptions added in <code>on</code>.</dd>
   *
   *   <dt><code>delegate</code></dt>
   *       <dd><code>function (node, subscription, notifier, filter)</code> The
   *       implementation logic for subscription via <code>Y.delegate</code> or
   *       <code>node.delegate</code>.  The filter is typically either a selector
   *       string or a function.  You can use
   *       <code>Y.delegate.compileFilter(selectorString)</code> to create a
   *       filter function from a selector string if needed.  The filter function
   *       expects an event object as input and should output either null, a
   *       matching Node, or an array of matching Nodes.  Otherwise, this acts
   *       like <code>on</code> DOM event subscriptions.  Store subscription
   *       related objects and information on the <code>subscription</code>
   *       object.  When the criteria have been met to fire the synthetic event,
   *       call <code>notifier.fire(e)</code> as noted above.</dd>
   *
   *   <dt><code>detachDelegate</code></dt>
   *       <dd><code>function (node, subscription, notifier)</code> The
   *       implementation logic for cleaning up a detached delegate subscription.
   *       E.g. detach any DOM delegate subscriptions added in
   *       <code>delegate</code>.</dd>
   *
   *   <dt><code>publishConfig</code></dt>
   *       <dd>(Object) The configuration object that will be used to instantiate
   *       the underlying CustomEvent. See Notifier's <code>fire</code> method
   *       for details.</dd>
   *
   *   <dt><code>processArgs</code></dt
   *       <dd>
   *          <p><code>function (argArray, fromDelegate)</code> Optional method
   *          to extract any additional arguments from the subscription
   *          signature.  Using this allows <code>on</code> or
   *          <code>delegate</code> signatures like
   *          <code>node.on(&quot;hover&quot;, overCallback,
   *          outCallback)</code>.</p>
   *          <p>When processing an atypical argument signature, make sure the
   *          args array is returned to the normal signature before returning
   *          from the function.  For example, in the &quot;hover&quot; example
   *          above, the <code>outCallback</code> needs to be <code>splice</code>d
   *          out of the array.  The expected signature of the args array for
   *          <code>on()</code> subscriptions is:</p>
   *          <pre>
   *              <code>[type, callback, target, contextOverride, argN...]</code>
   *          </pre>
   *          <p>And for <code>delegate()</code>:</p>
   *          <pre>
   *              <code>[type, callback, target, filter, contextOverride, argN...]</code>
   *          </pre>
   *          <p>where <code>target</code> is the node the event is being
   *          subscribed for.  You can see these signatures documented for
   *          <code>Y.on()</code> and <code>Y.delegate()</code> respectively.</p>
   *          <p>Whatever gets returned from the function will be stored on the
   *          <code>subscription</code> object under
   *          <code>subscription._extra</code>.</p></dd>
   *   <dt><code>subMatch</code></dt>
