Remove cells from blockMesh using topoSet + subsetMesh.

Remove elements from a mesh

1. Generate whole sphere mesh using blockMesh See tutorials/mesh/blockMesh/sphere

2. Delete half sphere mesh using topoSet + subsetMesh.
3. Step 2 generates an "oldInternalFaces", checkMesh, fails. Then I use createPatch to set "oldInternalFaces" as wall. checkMesh OK.
4. Use topoSet to generate an inlet using a cylinderToCell
5. Create inlet using createPatch
