This is a basic example on how to use the Predis\DispatcherLoop class.
To see this example in action you can just use redis-cli and publish some
messages to the 'events' and 'control' channel, e.g.:
./redis-cli
PUBLISH events first
PUBLISH events second
PUBLISH events third
PUBLISH control terminate_dispatcher
