Show HN: Mocaroni, Prototype a web API, auto-generate a mock server and docs

This idea came from a number of issues I've run into while working on projects dealing with unfinished APIs- Without a well established and disciplined process of communication, publishers of an API end up wasting time guessing what a consumer might need while the consumer is stuck trying to develop against a moving target. I think Mocaroni can help solve this problem. Let me know what you think!
