Initial commit of some express server code

[lossyrob]

This simply starts the repository off with a couple of nodejs files.

(Starting by going a bit overboard on conventions and stuff since you're new to Node.)

I placed the "server" component in it's own directory in preparation for having a couple different components in this repository that are tied together using docker compose.

Looks good. Everything worked for me in Docker Machine.

I'd go ahead and merge after making the additions to the Dockerfile, knowing that the test harness will change as we get going. No reason to keep the current state from holding us up though.

Merging, I'll get rolling on some real code to run/test.
