+Delay server works by issuing an HTTP GET request in the format:
+http://localhost:8080/[delay in ms]/[URL-encoded message]
+
+If an argument is passed in when delayserver is started, that
+argument will be used as the URL instead of 'localhost'.
+
+Upon receiving a request, it immediately reports the following to the console:
+
+{Message #} - {delay in ms}: {message}
+
+The server then delays the response for the requested time and echoes the message back to the caller.
