/**
 * This class provides a model for the data returned by the GeoIP2 Country
 * end point.
 *
 * The only difference between the City, City/ISP/Org, and Omni model
 * classes is which fields in each record may be populated. See
 * http://dev.maxmind.com/geoip/geoip2/web-services more details.
 *
 * @property \GeoIp2\Record\Continent $continent Continent data for the
 * requested IP address.
 *
 * @property \GeoIp2\Record\Country $country Country data for the requested
 * IP address. This object represents the country where MaxMind believes the
 * end user is located.
 *
 * @property \GeoIp2\Record\MaxMind $maxmind Data related to your MaxMind
 * account.
 *
 * @property \GeoIp2\Record\Country $registeredCountry Registered country
 * data for the requested IP address. This record represents the country
 * where the ISP has registered a given IP block and may differ from the
 * user's country.
 *
 * @property \GeoIp2\Record\RepresentedCountry $representedCountry
 * Represented country data for the requested IP address. The represented
 * country is used for things like military bases or embassies. It is only
 * present when the represented country differs from the country.
 *
 * @property \GeoIp2\Record\Traits $traits Data for the traits of the
 * requested IP address.
