Detailed Description

template<class VECTOR>
class MGSmootherIdentity< VECTOR >

Smoother doing nothing. This class is not useful for many applications other than for testing some multigrid procedures. Also some applications might get convergence without smoothing and then this class brings you the cheapest possible multigrid.
