Add Hello World node app

This is similar to what is documented here:

	https://medium.com/@adnanrahic/hello-world-app-with-node-js-and-express-c1eb7cfa8a30

but with some more modern content as recommended by Richard.

This can be run with:

	node server

in the current directory, (and then pointing a user agent at localhost:3000).
