implements FMClassificationTrainingSummary

FMClassifier training results.

param: predictions dataframe output by the model's transform method. param: scoreCol field in "predictions" which gives the probability of each instance. param: predictionCol field in "predictions" which gives the prediction for a data instance as a double. param: labelCol field in "predictions" which gives the true label of each instance. param: weightCol field in "predictions" which gives the weight of each instance. param: objectiveHistory objective function (scaled loss + regularization) at each iteration.
