> (For version 0.2)
> At present, if there are multiple receivers for a particular address,
> Dispatch delivers a copy of each message to all of the receivers. This
> feature adds the ability to by-configuration deliver messages to only one of
> those receivers.
> The configuration for this feature is per-address and defines two settings:
> - _fanout_ is either Multiple or Single (and a placeholder for Group).
> Multiple fanout means all subscribers receive each message. Single fanout
> means that only one subscriber receives the message.
> - _bias_ controls how single-fanout is treated. The following values for
> bias are provided:
> -- _Closest_ - each message is delivered to the closest/least-cost
> subscriber.
> -- _Spread_ - messages are spread indeterminately across all subscribers.
> -- _Latency_ - (not implemented yet) Messages are delivered in a balanced
> way to all subscribers based on the latency of acknowledgements. This mode
> attempts to keep all subscribers equally fed with incoming messages.
