> GBTClassifier is missing \{{featureSubsetStrategy}}.  This should be moved to {{TreeEnsembleParams}},
as in Scala, and it will then be part of GBTs.
> GBTClassificationModel is missing {{numClasses}}. It should inherit from {{JavaClassificationModel}}
instead of prediction model which will give it this param.
