Undefined type 'AbstractClass' in BaseModel.php

wp-orm/src/BaseModel.php

Line 100 in 17b8010

} elseif ($value instanceof AbstractClass) {

I think this line should be } elseif ($value instanceof BaseModel) { because you want to call primary_key() as the flattened value in case a property is a type of object that is a subclass of BaseModel, and also because AbstractClass is undefined.

Also @brandonwamboldt, I saw this code being used in a plugin called uListing from a theme I purchased recently from StylemixThemes. Thought you should know.
