Timestamp microservice Completed with PHP
User Stories:
  1. 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)
  2. If it does, it returns both the Unix timestamp and the natural language form of that date.
  3. If it does not contain a date or Unix timestamp, it returns null for those properties.
Example Usage:
cewjr.us/UnixTimestamp/timestamp.php/December 14,2015
cewjr.us/UnixTimestamp/timestamp.php/1450137600

Example Output:
{
"Unix Date": 1450137600,
"Natural Date": "December 14, 2015"
}
