  1. if QP does not have a nullspace matrix QPTDualize will try to compute one with MUMPS
  2. if empty nullspace matrix is attached/computed by QPTDualize the dual problem has an empty (unnecessary) linear equality constraint

OK, I think I will be able to solve this.

@jkruzik I feel like this should be solved first, together with an example, so that we are confident this works OK. Then having only inequality linear constraints, like in #12, is another level.
