* onPause User event fired to indicate a pause lifecycle event
* onDestroy* Internal event fired when app is being destroyed (User should use window.onunload event, not this one).

* The events marked with an * are sticky. Once they have fired, they will stay in the fired state.

* pause App has moved to background
* resume App has returned to foreground

* document.addEventListener("resume", myResumeListener, false);
* document.addEventListener("pause", myPauseListener, false);
