/**
* From the Spec, an EventRouter is:

* The event router is channel based, with rules based on longest-prefix match
* dispatching for registered listeners. The "/meta/*" channel is reserved for
* communications with the event router itself (including connection setup,
* tear-down, and re-connection), and all conformant clients and servers must

*
* * handshake
* * connect
* * reconnect
