Make Binary classification evaluator configurable

[Zruty0]

The following method:

        public BinaryClassifierEvaluator.CalibratedResult Evaluate(IDataView data, string label = DefaultColumnNames.Label, string score = DefaultColumnNames.Score,
            string probability = DefaultColumnNames.Probability, string predictedLabel = DefaultColumnNames.PredictedLabel)

needs to expose additional parameters from BinaryClassifierEvaluator.Arguments, or a delegate to set them.

I would like to have a go at this. So the relevant Evaluate method should have a BinaryClassifierEvaluator.Arguments as an additional parameter and we use it to set the private fields

private readonly Single _threshold; private readonly bool _useRaw; private readonly int _prCount; private readonly int _aucCount; private readonly int _auPrcCount; ?

In this case we might want to get rid of the Arguments args parameter in the constructor of BinaryClassifierEvaluator?

We have internalized that method so I think we can close this issue.
