This PDEFoam variant acts like a decision tree and stores in every cell the discriminant.
D = #events with given class / total number of events
as well as the statistical error on the discriminant. It therefore acts as a discriminant estimator. The decision tree-like behaviour is achieved by overriding PDEFoamDiscriminant::Explore() to use a decision tree-like cell splitting algorithm (given a separation type).
This PDEFoam variant should be booked together with the PDEFoamDecisionTreeDensity density estimator, which returns the events in a cell without sampling.

Internal subprogram used by Create.
It explores newly defined cell with according to the decision tree logic. The separation set via the 'sepType' option in the constructor.
The optimal division point for eventual future cell division is determined/recorded. Note that links to parents and initial volume = 1/2 parent has to be already defined prior to calling this routine.
Note, that according to the decision tree logic, a cell is only split, if the number of (unweighted) events in each daughter cell is greater than fNmin.
