00024 Class
00025     Foam::removeCells
00026 
00027 Description
00028     Given list of cells to remove insert all the topology changes.
00029 
00030     Works in two passes:
00031     - get faces that will become boundary faces
00032     - given these faces and the patches they have to go into make the
00033       changes.
