2. Make few important steps towards ROOT 6.23/01 ("New PYROOT"). Full adaptation is not yet achieved, there are some pending problems with effective inheritance from C++ classes (namely TSelector, PyPDF, PyVAR, ...). There are also some puzzling crashes...
3. rename tests, make test selection more transparent and easy to navigate back
4. rename ostap/fitting/selectors.py to ostap/fitting/pyselectors.py to avoid the name clash for python3
