README not up to date

[WeisLeDocto]

Hi there !

I tried to follow the instructions given in the README.md file for testing the module, but it failed right from the start with the following error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 7, in <module>
ModuleNotFoundError: No module named 'utilities'

The problematic lines seem to be these ones:

Bellatrex/README.md

Lines 75 to 76 in e56ec80

	from utilities import score_method, output_X_y
	from utilities import format_targets, format_RF_preds

I guess that this part of README.md was never updated since 69351d0.
My intent is just to bring it to your attention, as tutorial.ipynb seems the be the new correct way to follow the tutorial (although that is nowhere mentioned).

Cheers,
Weis

Hello!

tutorial.ipynb is indeed the new way to follow the tutorial. It is now updated with 0e9abcc
