> 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.
