choose a license for this example app

[wilkolazki]

Hi,

Your example application is a great websocket bootstrap resource. Thank you for your work. The problem is one might be tempted to copy-paste fragments of your code. This is, however, illegal until you grant your users some kind of license.

Please choose some kind of open source license, possibly one that allows including in closed-source software, so others might copy-paste with clear conscience.

Best regards, Szymon Wilkołazki

Good point. I'll update. Please use https://github.com/strongloop/loopback-next/tree/socketio instead.
