========

A test 3-d multigrid solver implementing the James algorithm for

isolated boundaries.

This is experimental.  The 3-d MG solver is based on the solver from

pyro.  The inhomogeneous Dirichlet BCs appear to work correctly,

converging as second-order when run via:

mg_test_inhomogeneous.py

That test problem was derived by picking the solution first and then

taking the Laplacian (via sympy) to get the RHS and evaluating the

boundary conditions as well.  This is shown in the notebook:
