During BlackoilStateDataHandle::gather we did read values from the
state where we should only receive values to. With this commit we
read from the state where we should send values.
Kudos to Bard for noticing this.
Previously BlackoilPropsDataHandle did hold a grid for sending
and receiving that were either not used or we could prevent their
usage. Therefore this commit removes them from the class and queries
all needed information from the property objects.
With this commit we add the possibility to start with a global representation
of a simulator that is read on each process and afterwards this presentation
is redistributed among the processors together with the properties and
state data needed to initialize the simulation.
There still is no parallel well handling and no parallel output. But with the
equilibrium example of @dr-robertk and deactivated output we can already
perform parallel runs.
