-Testcase for directional and automatic gap refinement. The geometry
-is two nested boxes
-with a single small pipe between them.
-
-- 1 cell initial mesh
-- consistent normal orientation of surface so
-  specify a 'gapMode' to limit refinement only to
-  gaps on the 'outside' of the surface
-- directional refinement
