Improve the mirroring of JSON schema into Python classes.

[marcofavorito]

Is your feature request related to a problem? Please describe.

Currently, the mirroring of the JSON schemas into classes is not very robust to schema changes.

Describe the solution you'd like

I'd like an automatic way that from JSON schema generates the Python classes to work with.

E.g. something like python-jsonschema-objects.

Describe alternatives you've considered

A similar self-made implementation with only the features we desire.
