    An interface for handling analytics events collected by an Analytics object.

    For basic analytics logging you can implement this interface and add your

    For more advanced logging you may want to subclass
    ThreadedAnalyticsDestination instead, which is more suitable for interacting
    with web servers and other time consuming destinations.
