        public void cleanup()
        Description copied from interface: IBolt
        Called when an IBolt is going to be shutdown. There is no guarentee that cleanup will be called, because the supervisor kill -9's worker processes on the cluster.

        The one context where cleanup is guaranteed to be called is when a topology is killed when running Heron in simulator.
