 * Added support for the GeoIP2 Anonymous IP database. The
   `GeoIP2\Database\Reader` class now has an `anonymousIp` method which returns
   a `GeoIP2\Model\AnonymousIp` object.
+* Boolean attributes like those in the `GeoIP2\Record\Traits` class now return
+ `false` insteadof `null` when they were not true.
