- f[0] ordering on patch faces to be ok.
Works by constructing equivalence lists for all the points on processor
patches. These list are in globalIndex numbering (so consecutively numbered
per processor)

E.g.

((7 93)(4 731)(3 114))
@endverbatim
means point 93 on proc7 is connected to point 731 on proc4 and 114 on proc3.
It then gets the lowest numbered processor (the 'master') to request a
sharedPoint label from processor0 and it redistributes this label back to
the other processors in the equivalence list.
It then assigns the lowest numbered processor to be the local 'master' and
constructs a mapDistribute to send all data to this master.
Algorithm:
- get meshPoints of all my points on processor patches and initialize

endloop until nothing changes
At this point one will have complete point-point connectivity for all
points on processor patches. Now
- (optional)remove point equivalences of size 2. These are
just normal points shared between two neighbouring procPatches.
- collect on each processor points for which it is the master
- request number of sharedPointLabels from the Pstream::master.
This information gets redistributed to all processors in a similar way
as that in which the equivalence lists were collected:
- initialize the indices of shared points I am the master for
loop
- send my known sharedPoints + meshPoints to all neighbours
- receive from all neighbour. Find which meshPoint on my processor
the sharedpoint is connected to
- mark indices for which information has changed
endloop until nothing changes.
points on processor patches. Now (optionally) remove point
equivalences of size 2. These are just normal points shared
between two neighbouring procPatches.
Note: the data held is either mesh point labels (construct from mesh only)
or patch point labels (construct from mesh and patch).
