Odd logic for treatment of blockMesh zones to sets

In the blockMesh application (around line 360 or so), the cell zones are written as sets (for ease of processing). Immediately after this, a mesh.removeFiles() is invoked prior to writing the mesh. Since the polyMesh::removeFiles also removes the sets sub-directory, it doesn't look like the sets will survive very long.

Tagged in @Mattijs since he might have an idea.

blockMesh.C

Writes the cellZone after writing the mesh. Works ok on my simple testcase.

As discussed with @mark - look into after release of v1612+

• possibly add -writeSets option to write the sets prior to clear-out

Milestone changed to %Version v1706
