Rework Product Classes

[HCookie]

The current product classes are a mess, inheritance worked and now it does not.

We need to be able to compose different modifications to the config and graphs

Possible Mixins

• ExportMixin
• EnsembleMixin
• GenericParamMixin

Properties that need to be defined

• model_assumptions - (could be done dynamically)
• form_fields
• qube

each product needs a concrete execute function

[HCookie]

Likely this will not need an update to the frontend, as the product itself provides the definition to the frontend for the configuration. However, we may end up extending with multi stage configs, and that then will.
