 What's the benefit/motivation for  passing in the packed matrix and primal
solution as oppose to a reference to the solver interface?

Sounds like a good idea...

While we are talking about ideas: I propose to add a couple of more
generateCuts() methods to the cut generator base class. Basically I'd like
to
make it possible to pass in the problem description and solution in some
other
way than passing in a solverinterface. Like passing in a packed matrix and
a
pointer to the primal solution, or passing in a set of pointers (i.e., a
C-style interface).

Any objections?
