Enhancement:
 - Adding preliminary support for polyhedra via face/cell decomposition
 - Parallel support is not yet complete
Bug-fix:

 - Need to check edge patch during map update.
 - Minor update of ReadMe.
Porting modifications:

 - Make branches more consistent.
Bug-fix:

 - Ensure that sync succeeds.
Refactoring:

 - Remove unused code.
Refactoring:

 - Consistent use of match tolerance.
 - Other porting changes.
Enhancement:

 - Simplify faceEdges modifications: now grouped with insertFace.
 - Remove trisectFace (to be looked at later)
Bug-fix / Enhancement:

 - Reverse maps need to be allocated for sub-meshes
 - Allow non-uniform spring-constants for surface smoothing
Repository management:

 - Remove SixDOF from version control.
 - Modifications to parallel debug options for sync.
Bug-fix:

 - Handle certain situations where both points of the edge lie on
   a lower-ranked processor patch, but not the edge itself. Such
   edges should be added to the coupled stack.
 - Fix incorrect logic for setting of debug flags in parallel.
Adding a marked-down ReadMe
Bug-fix:

 - Ensure that sizes match, since matchPoints can work with subsets
Sync / Bug-fix:

 - Added check for edge-edge conflicts
Back-port:

 - Cherry-picked commits and bug-fixes from Port-2.2.x
Enhancement:

 - Allow user-specified / random processor priority
 - Work-in-progress. Needs to be tested.
Bug-fixes:

 - Back-porting fixes from Port-2.2.x
Bug-fix:

 - Handle orphan faces correctly in parallel 2D
Bug-fix:

 - PointMap fix from Port-2.2.x
 - Minor ReadMe update
Bug-fix:

 - Handle situation where processor patches are being converted
   to physical ones. Back-ported from Port-2.2.x
