Small DecisionTree updates: * Changed main DecisionTree aggregate to treeAggregate. * Fixed bug in python example decision_tree_runner.py with missing argument (since categoricalFeaturesInfo is no longer an optional argument for trainClassifier). * Fixed same bug in python doc tests, and added tree.py to doc tests.
