# Demonstrates a basic module mixin and a slightly advanced meta technique:
# the use_socket (line 13) wrapper method connects to a server and issues
# various SocketIO commands. I use instance_eval (line 16) with a recipient
# SocketIO object, not an instance of the caller (NodeMessenger).
# instance_eval runs the passed block with receiver of self, which is a
# SocketIO object.

# The general purpose of this code is to talk to a Socket.io server
