**stochastic_heat2d_test**,
a C++ program which
calls stochastic_heat2d() to solve the steady state heat equation in a 2D
rectangular region with a stochastic heat diffusivity,
using the finite difference method (FDM), and stochastic model
from Babuska, Nobile and Tempone, using GNUPLOT to illustrate
the results.
