Update/refactor to separate config from app code maps 38

This moves project config into an example folder and sets up the tooling to load config from a remote http location.

set config url something like:
```
export CONFIG_URL=localhost:3002
```

And then build bundles with:
```
npm run build
```

Yea that was there because its the recommended way to setup node apps on heroku apparantly. Can move the build to a bash command in the Procfile though I think
