Example 4: addmesh / delete

The objective is to create a mesh using the addmesh/delete command by
deleting one mesh from another.

Two cubes, one smaller than the other, each having a different grid resolution are combined. The delete option finds the elements of mesh1 that intersect
mesh2 and removes them from mesh1, creating the resultant mesh (mesh3).
