Cookbook9 can be converted to multigrid solver once appropriate parameters (*solver.mesher.levels=2 and *solver.vsolver.Solver=multigrid) are added. However, the embedded solver will converge incorrectly. Setting esolver.vsolver.accuracy=6e-3 seems to fix the problem.

Added support of multigrid solver in Exchanger. Lifted the solver assertion in Coupler.
