[Cbc] Variables Names and Preprocess

[Robinson]

Hello everyone!
I'm having some troubles (2 in fact) and I hope someone could guide me.

1) Suppose I've created a class MyHeuristic extended from CbcHeuristic. Now,
would I be able to recover the variables names from inside
MyHeuristic::solution(...) method? I've wrote my code based on driver4.cpp.
Even setting osidiscipline to 2 it won't work. It prints the default names
only (from solution(...) method).

2) There is a way(inside Cbc) to know which columns were dropped after the
preprocess?

Thanks!
