Is there example "inheritance class in zephir from external class" ?

[dox07]

Hello.

I am going to make extension. And some of code should be moved from native php to zephir language. This code is some classes that inheritance from Yii framework classes, for example yii\base\Widget, \yii\db\ActiveRecord, etc. But Yii framework classes is in php source code and is not in any extensions.

Can i use like this in zephir language:

class Tariff extends \yii\db\ActiveRecord
{
.......
}

Thanks.
