   To run, type python3 URLShortener.py. On a another terminal window, type: curl localhost:5000/url '{"url": "https://www.github.com"}' and you will receive back a JSON with the original URL and its shortened version.

   Next step: when trying to access the URL, it should give you a status 301 message with the original location.
