0011  *      Class PDEFoamDiscriminantDensity is a class representing                  *
0012  *      n-dimensional real positive integrand function                            *
0013  *      The main function is Density() which provides the event density at a      *
0014  *      given point during the foam build-up (sampling).                          *
