Detailed Description

Direct mesh changes based on v1.3 polyTopoChange syntax.

Instead of recording changes and executing them all in one go (as did v1.3 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:

polyTopoChange can be copied.
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 can only use already existing 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 vector::max (VGREAT,VGREAT,VGREAT). 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.

		const bool	orderPoints = `false`
	)

Inplace changes mesh without change of patches.

Adapts patch start/end and by default does parallel matching. Clears all data. Returns map. inflate = true : keep old mesh points. Put new points into the returned map (preMotionPoints) so we can use inflation. Any points out of nothing (appended points) are vector::zero. inflate = false: set mesh points directly. Empty preMotionPoints in the map. orderCells : whether to order the cells (see bandCompression.H) orderPoints : whether to order the points into internal first followed by boundary points. This is not fully consistent with upper-triangular ordering of points and edges so is only done when explicitly asked for.
