Build ROC using roc_curve for sklearn and TMVA
Build ROC using roc_curve for sklearn and TMVA

I actually realized that one can use metrics.roc_curve not only for
probabilities only but also for BDT output score like it’s returned by
EvaluateMethod(“BDT”) from TMVA. This means I don’t need to have
private ROC curve implementation to perform sklearn (covered with
skTMVA) vs TMVA comparisons.
