Integration of Information Metrics

Some metrics are another files (e.g. `mi_entropy_gauss`, `redef_HC`), this is not compatible with entire BAMT logic.
Therefore, these files must be decomposed and integrated as Builders in BAMT Logic.

- [ ] mi_entropy_gauss.py
- [ ] redef_HC.py
- [ ] redef_info_scores.py
- [ ] discretization.py
- [ ] graph.py
- [ ] numpy_pandas.py

These files must be investigated and removed, their essence must be consolidated by BAMT.
