> For the BinaryClassificationEvaluator, the scaladoc doesn't mention that "areaUnderPR" is supported, only that the default is "areadUnderROC".
> Also, in the documentation, it is said that:
> "The default metric used to choose the best ParamMap can be overriden by the setMetric method in each of these evaluators."
> However, the method is called setMetricName.
