    Instructions:

npm install express faye-websocket ssh2 term.js
Create a public subdirectory
Place client.htm in public
Edit the ssh connection details in server.js. See the documentation for the connect() method in the ssh2 readme for more information.
Start the server with node server.js
Visit http://localhost:8000/client.htm in a WebSocket-capable browser
