11 * Class for decision tree like PDEFoam. It overrides *
12 * PDEFoam::Explore() to use the decision tree like cell split *

This PDEFoam variant acts like a decision tree and stores in every cell the discriminant.
virtual void Explore(PDEFoamCell *Cell)
Internal subprogram used by Create.
PDEFoamDecisionTree()
Default constructor for streamer, user should not use it.
virtual ~PDEFoamDecisionTree()
Destructor deletes fSepType.
