Enable IBM Cloud Deployment

[bradley-holt]

Enable deployment to IBM Cloud. This should be implemented as a Node.js app that serves static files, likely using Express. The Polymer + PouchDB implementation can be use for reference:

Note that this is just one deployment option. The app can still be deployed to GitHub Pages or simply run locally.
