Add average ROC function + test

[Rubenkl]

Function to average ROC curves using vertical thresholding by fixing the FP rate.
Test also added, but unsure if these will run automatically somehow?

Thanks!

The tests are only failing on code style, could you install black==19.10b0 and run it on your changes? https://github.com/psf/black

The implementation looks good to me but @silvandeleemput would you be able to review?

As discussed, I would recommend adding:

• the required keyword arguments
• a fixture for fixing the random seed

LGTM

I get this error when I do from evalutils.roc import average_roc_curves. Is there a bug that needs to be fixed?

This commit is not yet in the latest release. Try installing and/or running this command to get the function:
pip install -U git+https://github.com/comic/evalutils@master

Ah, you're right! Hang on I will make a new release

Ok, 0.2.4 released and is on pypi which includes this function, @kiranvaidhya please upgrade.
