C6H6 system - parallelized

A parallelized structure search calculation for a C6H6 system using GOFEE. Files are available in the test-suite provided.

The degree of parallelization is based on MPI and can be controlled using the

mpirun -np $NSLOTS python input_c6h6_parallel.py

command. The input file is the same as in the previous case, but we change the jobscript.
