Simple is really the descriptive name for the layer
Sure, it is "virtual" but that is not as important as the fact that it is simple (or simplified)
Also objct (based really) is better, since orientated implies it is a little like that, but only orientated, not really it. Sol only has objects, nothing else
Just cause i was renaming anyway
opted to hack require to be getting on
need require for the test helper
and the files in lib/parfait
General require mechanism would still be ok, but require_ralative means implementing file source, which needs to be dragged around. I'll make an issue
