docs: Specifies a class that should be called each time the <code>BeaconService</code> gets ranging
  data, which is nominally once per second when beacons are detected.
  <p/>
  IMPORTANT:  Only one RangeNotifier may be active for a given application.  If two different
  activities or services set different RangeNotifier instances, the last one set will receive
  all the notifications.
