The name "tilt_profile" implies too much (like some kind of conceptual completeness). But we need a class that simply assumes the columns companies_id, product, and company -- whatever their contents so that intermediate results are acceptable.
We need a more friendly, and general constructor of the form tilt_levels(product, company). Maybe just add the class "nest_levels"?
