Description

BM25 is now the default similarity, but the more like this is still using the old TF/IDF .

This issue is to move to BM25 and refactor the MLT to be more organised, extensible and maintainable.

Few extensions will follow later, but the focus of this issue will be :

• BM25
• code refactor + tests
