Topic objects implement a pub/sub paradigm.
Sessions subscribe to the paths they are interested with calls to topic.sub passing a pipeid (see pipe).
Other sessions publish messages to a path that all subscribers will receive. This is done with calls to topic.pub.
When a session is no longer interested in a topic it unsubscribes from it with a call to topic.unsub.
