FCC Basejump: Timestamp Microservice

User stories:

• I can pass a string as a parameter, and it will check to see whether that string contains either a unix timestamp or a natural language date (example: January 1, 2016)
• If it does, it returns both the Unix timestamp and the natural language form of that date.
• If it does not contain a date or Unix timestamp, it returns null for those properties.

Example usage:

https://edcheung-fcc-timestamp.herokuapp.com/Jan 29, 2016
https://edcheung-fcc-timestamp.herokuapp.com/1-29-16
https://edcheung-fcc-timestamp.herokuapp.com/January 29, 2016

Example output:

{ unix: 1454047200, natural: "January 29, 2016" }
