11  * Class PDEFoamDiscriminantDensity is a class representing *
12  * n-dimensional real positive integrand function *
13  * The main function is Density() which provides the event density at a *
14  * given point during the foam build-up (sampling). *

This function is needed during the foam buildup.
This is an abstract class, which provides an interface for a PDEFoam density estimator.
This is a concrete implementation of PDEFoam.
