class CurrentCountry in Price 8

Holds a reference to the current country, resolved on demand.

The ChainCountryResolver runs the registered country resolvers one by one until one of them returns the country. The DefaultCountryResolver runs last, and will select the site's default country. Custom resolvers can choose based on the user profile, GeoIP, etc.
