feature/richer-domain

This is the corresponding code of the bachelor's thesis "Learning Domain-Specific Predicates in Decision Trees for Explainable Controller Representation" written by @christoph.weinhuber.

Among other features, it also contains the concept of Richer Domain Predicates (with Coefficients and Feature Constraints), as well as several different decision tree induction algorithms (like a semi-automatic strategy aka a CLI to build custom DTs).

For a quick overview, I attached the slides of my thesis presentation.
