[~mengxr] Would you mind to give some comments on how to design this api?

> Implement a wrapper in SparkR to support decision tree regression. R's naive Decision Tree Regression implementation is from package rpart with signature rpart(formula, dataframe, method="anova"). I propose we could implement API like spark.rpart(dataframe, formula, ...) . After having implemented decision tree classification, we could refactor this two into an API more like rpart()
