void setUnrefinement ( const labelList &  masterFaces,
polyTopoChange &  meshMod,

Map< label > &  restoredCells 
)

Play commands into polyTopoChange to reinsert original faces.

No other topo changes can be done inbetween setRefinement and setUnrefinement. Can be called multiple times to undo parts of the last setRefinement call. Gets the master face labels whose sets need to be restored. Returns maps from added restored point to original point label (i.e. content of savedPointLabels_). (only restoredPoints are actually set; rest are just for generalness). See note above about restoring faces from different patches (mergeAcrossPatches)
