I needed som additional features like inheritance...

- string property with format uri and byte
- object property
- inheritance (see swagger.json)
- additional arguments (model/api package)
- some NPE eliminated

I saw that you're working on implementing inheritance, too, My soulution is rather quick an dirty an I also considered to use ComposedModel. I think, the loops creating the models should be refactored completely.
