enable CORS

[rolandjitsu]

I was just trying your API with Angular 2 HTTP, but it seems that you do not have CORS enabled, so my XHR fails with:
XMLHttpRequest cannot load https://newton.now.sh/sin/8. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access.

Ah, I see the error. I'm on it right now.

There we go! The most recent commit should fix that for you. Check your app again and let me know if the problem persists.
