Live demos

[zachbutton]

We need demos of crystalize.js to place in the Samples section of the readme.

They should be fully qualified demos:

• Located in ./samples/[your-demo-name]
• Contain their own package.json and started via npm start
• Contain their own README.md with at least a summary of what it is

Big demos, small demos, frontend, backend... It doesn't matter, making this a #goodfirstissue.
