 * ## Usage ##
 *
 * The basic API for this class is the same for every database. First, you
 * create a reader object, specifying a file name. You then call the method
 * corresponding to the specific database, passing it the IP address you want
 * to look up.
 *
 * If the request succeeds, the method call will return a model class for
 * the method you called. This model in turn contains multiple record classes,
 * each of which represents part of the data returned by the database. If
 * the database does not contain the requested information, the attributes
 * on the record class will have a `null` value.
 *
 * If the address is not in the database, an
 * {@link \GeoIp2\Exception\AddressNotFoundException} exception will be
 * thrown. If an invalid IP address is passed to one of the methods, a
 * SPL {@link \InvalidArgumentException} will be thrown. If the database is
 * corrupt or invalid, a {@link \MaxMind\Db\Reader\InvalidDatabaseException}
 * will be thrown.
