Country.Unsafe

This module provides the data constructor for a Country. While pattern matching on a country is perfectly safe, constructing one is not. There is an invariant the type system does not capture that the country number, as defined by ISO 3166-1, is between the inclusive bounds 0 and 999. Failure to maintain this invariant can cause other functions in this library to segfault.
