------------------------------------------

But [~fliang] if you have a chance, then it'd be a good Spark package!

> The Pipelines API will make it easier to create a generic Bagging algorithm which can
work with any Classifier or Regressor.  Creating this feature will require researching the
possible variants and extensions of bagging which we may want to support now and/or in the
future, and planning an API which will be properly extensible.
> Note: This may interact some with the existing tree ensemble methods, but it should be
largely separate since the tree ensemble APIs and implementations are specialized for trees.
