Typedefs
using	dftefe::utils::mpi::ErrorCode = int
	The following provides a unified framework to use typedefs that will be valid both with and without the use of an MPI library. This allows the user to write application code in terms of the following typedefs, and as a result, compile the code successfully both with and without MPI. The idea is that while not using an MPI library, we uses aliases (typedefs) for the MPI datatypes (e.g.m MPIFloat, MPIByte, etc.) On the other hand, while not using an MPI library, the same aliases are equated to int (integer). The choice of int is arbitrary, one can use any other low-memory datatype (e.e., char, unsigned cha, etc) More...
