No longer WIP :)
Motivation
This adds matrix-free grid transfers to MueLu. Officially, this adds two classes:
MatrixFreeTentativePFactory_kokkosandMatrixFreeTentativeP_kokkos. These are two kokkos-based classes, one deriving fromPFactoryand one deriving fromXpetra::Operator. Unfortunately, this requires the Kokkos refactor as it depends on Kokkos views obtained from theAggregates_kokkosobject.Limitations
I'm planning to touch up a lot of these limitations as time goes on, but I'm hoping to get this merged this week so I can add a
MatrixFreeTentativeRAPFactoryso I can actually test the matrix-free hierarchy.
