> The Scala StringIndexerModel has an alternate constructor that will create the model
from an array of label strings.  This should be in the Python API also, maybe as a classmethod
> {code:java}
> model = StringIndexerModel.from_labels(['a', 'b']){code}
> See SPARK-15009 which added a similar constructor to CountVectorizerModel
