[Users] Multigrid elliptic solver released.

Dear Cactus and Einstein Toolkit users, I have been working on a solver for elliptic PDEs based on the multigrid paradigm, and developed as a Cactus thorn using Carpet. The solver is now able to tackle some basic problems and could be applied to other cases of interest to this community. You
