class TMVA::PDEFoamDecisionTree: public TMVA::PDEFoamDiscriminant


 PDEFoamDecisionTree

 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.

PDEFoamDecisionTree()

 Default constructor for streamer, user should not use it.

PDEFoamDecisionTree(const TString& , TMVA::SeparationBase* sepType, UInt_t cls)

 Parameters:

 - name - name of the foam

 - sepType - separation type used for the cell splitting (will be
   deleted in the destructor)

 - cls - class to consider as signal when calcualting the purity

PDEFoamDecisionTree(const TMVA::PDEFoamDecisionTree& )

 Copy Constructor  NOT IMPLEMENTED (NEVER USED)

~PDEFoamDecisionTree()

 Destructor
 deletes fSepType

void Explore(TMVA::PDEFoamCell* Cell)

 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 dautghter
 cell is greater than fNmin.
