As it turns out initializing the Geology on a distributed grid
result in wrong values for e.g. saturation. Therefore with this
commit we resort to initializing the global geology and distribute
it using communication.
Previously we used the size of the communicator within the CpGrid to check
whether we are running in parallel and need to redistribute the grid.
Unfortunately, this is MPI_COMM_SELF until we actually loadbalance and redistribute.
Therefore we now use the size of the MPI_Helper (i.e. MPI_COMM_WORLD) which
gives us the number of all available processes.
Note that the wrong behaviour was provoked with 656e5de331. Before that we
redistributed in any case which luckily included runs with more than 1 process.
Any argument that is not handled by the parameter parser will
be assumed to be a deck filename. Only one is accepted, and if
given, it will override any deck_filename=<something> on the
command line or in parameter files.
FYI:
The parameter parser handles arguments of the following types:
key=value (note no space around = or in strings)
parameterfile.xml
parameterfile.param
