iz 
All your type checking in one place. This intended to serve as simple sanity checking for
common formats: IP addresses, zip codes, credit cards, phone numbers, etc. This isn't
intended to be the authoritative source on what each of these types are. It seeks to determine
whether 'foobar', '(555) 123 - 4567', and nil are phone numbers, or if wefwef looks
like an email.
Compatible with Ruby 1.8 - 2.2.
