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