> Currently, in spark.mllib, generalized linear regression models like LinearRegressionModel,
RidgeRegressionModel and LassoModel support predict() via: LinearRegressionModelBase.predict,
which only takes single rows (feature vectors).
> It should support batch prediction, taking an RDD.  (See other classes which do this
already such as NaiveBayesModel.)
