{- About the test result values.
Running "cabal test" does not verify that the results do the intended
thing in OpenSCAD. Possibly we'll add shell tests for that at some
point, but not yet.
For now, if you change or add strings, please manually copy them into
OpenSCAD and make sure they do what you want the Model data structure
that they are testing does.
