This code is similar to the JavaScript on the Agent application. The connect() function gets a WebSocket
and sends the initial sign-on message and then wires-up the onmessage and onclose event handlers. The send()
function sends the text that was entered to the server and echoes it on the page. The displayMsg() function is the
event handler for the processing incoming messages from the server, which are displayed on the page.
