DUnit Compatibility in Smoketest

To address some odd concerns about differences between DUnit and Smoketest, I thought it would be useful to demonstrate how it is entirely within the gift of a Smoketest user to create their own “comfort” layer, to make using Smoketest more similar to the DUnit framework if they wish (though why in that case they wouldn’t simply use DUnit, I can’t quite fathom. But still).
