> Add a setBins method for BinaryClassificationMetrics.
> BinaryClassificationMetrics is a class in mllib/Evaluation. numBins is a key
> attribute of it. If numBins greater than 0, then the curves (ROC curve, PR
> curve) computed internally will be down-sampled to this many "bins".
> It is useful to let the user set the numBins.
