Description
Direct mesh changes based on polyTopoChange syntax.

Instead of recording changes and executing them all in one go (as does
polyTopoChange) this class actually holds the current points/faces/cells
and does the change immediately.
It can be asked to compress out all unused points/faces/cells and
renumber everything to be consistent.

Note:
- adding a face using non-existing cells causes all intermediate cells
to be added. So always first add cells/points and then faces.
(or set strict checking)
- strict checking:
    -any added/modified face can only use already existing vertices
    -any added face                 ,,                     cells
    -no item can be removed more than once.
- removed cell: cell set to 0 faces.
- removed face: face set to 0 vertices.
- removed point: coordinate set to greatPoint (GREAT,GREAT,GREAT).
Note that this might give problems if this value is used already.
To see if point is equal to above value we don't use == (which might give
problems with roundoff error) but instead compare the individual component
with >.
- coupled patches: the reorderCoupledFaces routine (borrowed from
the couplePatches utility) reorders coupled patch faces and
uses the cyclicPolyPatch,processorPolyPatch functionality.
