// 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
