Detailed Description

Sends/receives parts of mesh+fvfields to neighbouring processors. Used in load balancing.

Input is per local cell the processor it should move to. Moves meshes and volFields/surfaceFields and returns map which can be used to distribute other.

Notes:

does not handle cyclics. Will probably handle separated proc patches.
if all cells move off processor also all its processor patches will get deleted so comms might be screwed up (since e.g. globalMeshData expects procPatches on all)
initial mesh has to have procPatches last and all normal patches common to all processors and in the same order. This is checked.
