Example 3 for DEALII, Modified Again

**STEP-3MOD2** is a second modification of the standard step-3 example.
The region is still the square, but now we want the exact solution to be
u(x,y) = x^2 * y. Since the original example uses a constant right
hand side of 1, and zero boundary conditions, it is necessary to
change the right hand side to -2*y, and change the boundary conditions
to x^2*y.

Files you might find useful:

- CMakeLists.txt, the file needed by cmake on my system.
- step-3mod2.cc, the source code for the example.
- step-3mod2.sh, a shell script which contains the commands to create the makefile and run the example.
- step-3mod2_output.txt, the output file.
- solution.eps, graphics information about the solution, in EPS format.
- solution.vtk, graphics information about the solution, which can be input to visit or paraview.
- solution.png, a PNG image of the solution Z(X,Y).
