Still does not compile. Problem with MPI.
Merge branch 'intel_phi' of https://github.com/bollig/rbffd_gpu into casiornis

Added the proper mpi library.
Note: whatever mpi library that is used, there must be an $include mpi.h, which
includes mpi.cxx, which defines a namespace MPI, which itself defines various types for MPI.
