+ * The doPageNavigation() function performs page navigations asynchronously,

+ *
+ *                uri: if !undefined, the browser will navigate to this uri
+ *
+ *               back: if true, the browser will execute goBack()
+ *
+ *            forward: if true, the browser will execute goForward()
+ *
+ *          gotoIndex: if a number, the browser will execute gotoIndex() with
+ *                     the number as index
+ *
+ *             reload: if true, the browser will execute reload()
+ *
+ *  eventsToListenFor: an array containing one or more of the following event
+ *                     types to listen for:  "pageshow", "pagehide", "onload",
+ *                     "onunload".  If this property is undefined, only a
+ *                     single "pageshow" events will be listened for.  If this
+ *                     property is explicitly empty, [], then no events will
+ *                     be listened for.
+ *
+ *     expectedEvents: an array of one or more expectedEvent objects,
+ *                     corresponding to the events which are expected to be
+ *                     fired for this navigation.  Each object has the
+ *                     following properties:
+ *
+ *                          type: one of the event type strings
+ *                          title (optional): the title of the window the

+ *                          persisted (optional): the event's expected
+ *                              .persisted attribute
+ *
+ *                     This function will verify that events with the
+ *                     specified properties are fired in the same order as
+ *                     specified in the array.  If .title or .persisted
+ *                     properties for an expectedEvent are undefined, those
+ *                     properties will not be verified for that particular
+ *                     event.
+ *
+ *                     This property is ignored if eventsToListenFor is
+ *                     undefined or [].
+ *
+ *     preventBFCache: if true, an RTCPeerConnection will be added to the loaded
+ *                     page to prevent it from being bfcached.  This property
+ *                     has no effect when eventsToListenFor is [].
+ *
+ *      onNavComplete: a callback which is notified after all expected events
+ *                     have occurred, or after a timeout has elapsed.  This
+ *                     callback is not notified if eventsToListenFor is [].
