Cool. Is there a substantial computational cost to only using A_in and A_ub?

I will probably never use lb and ub and A_lb.  I know they are in there for ML
compatibility, but I think they are actually more confusing then helpful, unless
they provide a speedup.

Yes.  I am not sure if my results will be useful, but it was definitely
interesting to learn how to use qp(), and I it would have been A LOT harder
without your help.
