@chkoar I made a quick implementation of a balanced random forest classifier.
I tried to keep the changes minimal. The issue is that most of the code rely that the base estimators are trees, calling some private functions. Therefore, we cannot easily use pipeline as in the bagging case.

If you could have a look at it. It would be nice to have a second opinion.

Note that this can work only with the release 0.20 which is the reason for the failing.

We don't implement this via Bagging in order to get feature importances out of the box, right?
