Parameters for the Krylov solvers are now set by the parameter system.

Example usage, affecting only PDE and its solvers:

  PDE pde(a, L, mesh, bc);
  pde.set("Krylov relative tolerance", 1e-14);
  Function U = pde.solve();

Alternative usage, affecting all Krylov solvers:

  PDE pde(a, L, mesh, bc);
  set("Krylov relative tolerance", 1e-14);
  Function U = pde.solve();
