Detailed Description

Class containing mesh-to-mesh mapping information after a change in polyMesh topology.

General:

pointMap/faceMap/cellMap:
from current mesh back to previous mesh. (so to 'pull' the information onto the current mesh)
reversePointMap/faceMap/cellMap:
from previous mesh to current. (so to 'push' information)

In the topology change points/faces/cells

can be unchanged. (faces might be renumbered though)
can be removed (into nothing)
can be removed into/merged with existing same entity (so point merged with other point, face with other face, cell with other cell. Note that probably only cell with cell is relevant)
can be added from existing same 'master' entity (so point from point, face from face and cell from cell)
can be appended: added 'out of nothing'.

All this information is necessary to correctly map fields.

points

unchanged:
- pointMap[pointi] contains old point label
- reversePointMap[oldPointi] contains new point label
removed:
- reversePointMap[oldPointi] contains -1
merged into point:
- reversePointMap[oldPointi] contains <-1 : -newPointi-2
- pointMap[pointi] contains the old master point label
- pointsFromPoints gives for pointi all the old point labels (including the old master point!)
added-from-same:
- pointMap[pointi] contains the old master point label
appended:
- pointMap[pointi] contains -1

faces

unchanged:
- faceMap[facei] contains old face label
- reverseFaceMap[oldFacei] contains new face label
removed:
- reverseFaceMap[oldFacei] contains -1
merged into face:
- reverseFaceMap[oldFacei] contains <-1 : -newFacei-2
- faceMap[facei] contains the old master face label
- facesFromFaces gives for facei all the old face labels (including the old master face!)
added-from-same:
- faceMap[facei] contains the old master face label
appended:
- faceMap[facei] contains -1

cells

unchanged:
- cellMap[celli] contains old cell label
- reverseCellMap[oldCelli] contains new cell label
removed:
- reverseCellMap[oldCelli] contains -1
merged into cell:
- reverseCellMap[oldCelli] contains <-1 : -newCelli-2
- cellMap[celli] contains the old master cell label
- cellsFromCells gives for celli all the old cell labels (including the old master cell!)
added-from-same:
- cellMap[celli] contains the old master cell label
appended:
- cellMap[celli] contains -1
