This PDEFoam variant 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. It should be booked together with the PDEFoamDiscriminantDensity density estimator, which returns the discriminant density at a given phase space point during the foam build-up.

This function fills an event into the discriminant PDEFoam.
The event weight 'wt' is filled into cell element 0 if the event is of class fClass, and filled into cell element 1 otherwise.

Project foam variable idim1 and variable idim2 to histogram.
The projection algorithm is modified such that the z axis range of the returned histogram is [0, 1], as necessary for the interpretation as a discriminator. This is done by weighting the cell values (in case of cell_value = kValue) by the cell volume in all dimensions, excluding 'idim1' and 'idim2'.
Parameters:
Returns: a 2-dimensional histogram
