Setup DSL for interaction with a user

We should generate an implementation with the model, w.g. generate a new class. A user should have access to this class. We can use Reflekt for example to find this class by a special annotation or something like this. This point should be discussed

No source file, test, or entry point is named. Start by clarifying the proposed generated class, user-facing DSL, and whether Reflekt or a special annotation is required; the issue is complete only after that design is agreed.
