To test this:

1. Run npm install or yarn install
2. Run node index.js && ssh -p 2222 cf:$(cf app app-name --guid)/0@ssh.system.domain.com, where app-name is your app name and ssh.system.domain.com is the DNS name of your SSH end point.
3. When prompted for a password, enter the code listed after Access Code is.

You should now be SSH'd into the given application & instance id.

NOTE: better error handling should be done, but has been omitted to keep this example brief.
