Find primal solution from dual one and vice-versa?

[dourouc05]

Sometimes, I would find it useful to have a way to get the primal solution from the dual one (and vice-versa), especially when I don't get this solution from a solver (read from a file, got from a heuristic, etc.). For instance, just solving the complementary slackness equations?

I would say that this is low priority: nice to have, but not necessarily soon.
