Class
    Foam::SmoothSolver

Description
    Iterative solver for symmetric and asymmetric matrices which uses a
    run-time selected smoother e.g. GaussSeidel to converge the solution to
    the required tolerance.  To improve efficiency, the residual is evaluated
    after every nSweeps smoothing iterations.
