 ##What
-Some iOS features require the user grant permission before you can access them.

 This library lets you check the current status of those permissions. (Note: it _doesn't_ prompt the user, just silently checks the permission status)

 `notificationPermissionStatus()` - checks if the user has authorized remote push notifications. Note: Apple only tells us if notifications are authorized or not, not the exact status. So this promise only returns `StatusUndetermined` or `StatusAuthorized`. You can determine if `StatusUndetermined` is actually `StatusRejected` by keeping track of whether or not you've already asked the user for permission.
