MueLu export functionality broken
Created by: tawiesn
Commit 67accd45 breaks the export or "DataToWrite" functionality. The problem is that
L->AddKeepFlag(name, &*levelManagers_[data[i]]->GetFactory(name));
assumes that there is a FactoryManager for each level. This is only guaranteed in the Easy parameter input deck but not in the Factory-based parameter input deck. (see lines 1673ff in MueLu_ParameterListInterpreter_def.hpp versus lines 360ff).
@csiefer2 Can you comment on this? I guess you added that code for exporting "pcoarsen: element to node map". Why do we need that for "A", "P"... where we don't really need a FactoryManager to access the data.
