Publisher, Requester, Responder and Subscriber all register the advertisement message in their instances.
Simplifies Requester's send interface.

Previously, one had to use the socket provided on the ready event to send a request. Now the Requester class's send method proxies its socket's send method.
Responder and Subscriber support namespaces.

Responder ignores messages that have another namespace than the Responder.
Subscriber enforces the namespace when listening for events.
Simplifies Publisher's emit interface.

Previously one had to emit to the socket provided by the Publisher in the ready event. Now Publisher proxies calls to its publish method to its socket itself.
Publisher and Subscriber support namespaces.
Cote depends on 0.0.8 tag of dashersw/node-discover.
Discovery uses its own instance uuid instead of process uuid at hello logger.
Examples include commented-out namespaces.
