David Calavera 434d2e8745 Add PubSub topics. ... A TopicFunc is an interface to let the pubisher decide whether it needs to send a message to a subscriber or not. It returns true if the publisher must send the message and false otherwise. Users of the pubsub package can create a subscriber with a topic function by calling `pubsub.SubscribeTopic`. Message delivery has also been modified to use concurrent channels per subscriber. That way, topic verification and message delivery is not o(N+M) anymore, based on the number of subscribers and topic verification complexity. Using pubsub topics, the API stops controlling the message delivery, delegating that function to a topic generated with the filtering provided by the user. The publisher sends every message to the subscriber if there is no filter, but the api doesn't have to select messages to return anymore.
