/**
* A StatisticsBrokerPlugin
* You can retrieve a Map Message for a Destination - or
* Broker containing statistics as key-value pairs The message must contain a
* replyTo Destination - else its ignored
* To retrieve stats on the broker send a empty message to ActiveMQ.Statistics.Broker (Queue or Topic)
* With a replyTo set to the destination you want the stats returned to.
* To retrieve stats for a destination - e.g. foo - send an empty message to ActiveMQ.Statistics.Destination.foo
* - this works with wildcards to - you get a message for each wildcard match on the replyTo destination.
* The stats message is a MapMessage populated with statistics for the target
