HealthKit UV exposure support

@developers Please support HealthKit, it would be convenient to use the location to write to the new uv index tab in HealthKit. Just a basic feature would be to write to HealthKit automatically the uv index depending on location throughout the day. This uv index is part of iOS 9. So it will be released this fall. iOS 9 is out please support HealthKit
