Random Forest

[thesps]

The RandomForestClassifier in scikit-learn is similar to the GradientBoostingClassifier in that an ensemble of Decision Trees is used. For binary classification tasks, I think conifer already works for RandomForestClassifiers. However, for multi-class problems, whereas GradientBoostingClassifier learns a different tree for each class at each 'estimator', the RandomForestClassifier trains a single tree with multiple output scores. So, RandomForestClassifier with multi-class problems won't work at the moment, but should not be too challenging to support.
