- Added AMG with krylov cylcle. Up to now it seems to be more scalable
int terms of number of iterations needed for convergence. Albeit the
time to solution does not improve that much because of intensive
copying.

@Markus: You have committed this rule beginning of August (and briefly removed
         it mid of August), but AFAICT you never committed
         "cvectorcmatrix.cc".  If you still have that file somewhere, can you
         please commit it and reinstate this rule?
