#plz ⇒ Object

The following method is a country-specific accessor to the the German Postleitzahl (PLZ). If returns the German postal code if the address is in Germany. Otherwise, it returns nil.

There are cases when the maps api can’t isolate the postal code. In this case, the ‘postal_code` returns `nil`. Try to get it from the regex then.
