+Description
+    Utility to remove faces (combines cells on both sides).
+
+    Takes faceSet of candidates for removal and writes faceSet with faces that
+    will actually be removed. (because e.g. would cause two faces between the
+    same cells). See removeFaces in dynamicMesh library for constraints.
