Description
The Krylov solvers currently availble in ISTL assume that preconditioners do not change between iterations. But often this is the case (e.g. using AMG with a non-direct solver the number of iterations of the coarse solver might change and therefore the whole AMG changes.)
To allow for changing preconditioners we should add flexible versions to ISTL
