Implemented for the benchmark to write the output of MatrixReader into the log file. BUG: Every other error message added into the Benchmark doesn't have a '!' as a prefix in the log file.

Changed TYPED_TEST_CASE to TYPED_TEST_SUITE, as per google test recommendation which said that TYPED_TEST_CASE is deprecated.

Copied tnl-benchmark-spmv files and spmv.h from BLAS to SpMV. Deleted min/max size and stepFactor. Not working yet, backup purposes.

It is either from subdomain boundary to overlap or vice versa.

Added macro TNL_MPI_PRINT_COND for conditional print outs.

Set-up of the distributed grid subdomains overlaps is taking the actualy applied periodic boundary conditions into account.
