Detailed Description

This class separates the mesh into distinct unconnected regions, each of which is then given a label according to globalNumbering().

Say 6 cells, 3 processors, with single baffle on proc1.

          baffle
            |
+---+---+---+---+---+---+
|   |   |   |   |   |   |
+---+---+---+---+---+---+
  proc0 | proc1 | proc2

1: determine local regions (uncoupled)

+---+---+---+---+---+---+
| 0 | 0 | 0 | 1 | 0 | 0 |
+---+---+---+---+---+---+
  proc0 | proc1 | proc2

2: make global

+---+---+---+---+---+---+
| 0 | 0 | 1 | 2 | 3 | 3 |
+---+---+---+---+---+---+
  proc0 | proc1 | proc2

3: merge connected across procs

+---+---+---+---+---+---+
| 0 | 0 | 0 | 2 | 2 | 2 |
+---+---+---+---+---+---+
  proc0 | proc1 | proc2

4. determine locally owner regions.

Determine compact numbering for the local regions and send these to all processors that need them:

proc0 uses regions:
- 0 which is local to it.
proc1 uses regions
- 0 which originates from proc0
- 2 which is local to it
proc2 uses regions
- 2 which originates from proc1

So proc1 needs to get the compact number for region 0 from proc0 and proc2 needs to get the compact number for region 2 from proc1:

+---+---+---+---+---+---+
| 0 | 0 | 0 | 1 | 1 | 1 |
+---+---+---+---+---+---+
  proc0 | proc1 | proc2

Can optionally keep all regions local to the processor.

Note: does not walk across cyclicAMI/cyclicACMI - since these are not coupled() at the patch level.
