Mpi multi dt fix

How about this as a fix for #124 (closed) ? The cell properties relevant for the density and force calculation are updated on the receiving side by re-constructing them from the particles.

mentioned in issue #124 (closed)

Added 1 commit:

• 740faaac - Check that the received particles are at the correct position in time.

Added 1 commit:

• 7cacb924 - Correct memcpy to use sizeof(int), not sizeof(type)

Added 1 commit:

• d91c870c - Removed check in the dorecv task

So that is a fix that should go in. It does not fully solve #124 (closed) nor #93 (closed) but it goes in the right direction.

Reassigned to @pdraper

Agreed these are all good. Will accept.

Status changed to merged

Finished with this branch?

I still have it alive with more non-pushed changes. Would rather keep it for now.

OK, it's all yours.
