Extendingcmodel?

Hi, is it possible to extend CModel?

PHPStorm only allows me to implement it, but not extend.

In the docs it's an abstract class, but so is CActiveRecord and I am able to extend from it.

I will use DB but not in ActiveRecord way, I need to access settings, which would be like this:

setting_name setting_value

post_per_page 2
admin_email email@e.com

What would you recommend?

Thanks!
