 // provides cross-browser focusin and focusout events 
 // IE has native support, in other browsers, use event caputuring (neither bubbles) 
  
 // provides delegate(type: String, delegate: Selector, handler: Callback) plugin for easier event delegation 
 // handler is only called when $(event.target).is(delegate), in the scope of the jQuery-object for event.target  
  
 // provides triggerEvent(type: String, target: Element) to trigger delegated events
