Pierre,
Look at the new example driver4b.cpp and see if you can understand it and
if it does something of what you want. It is only a first attempt.
I had to modify event handling in Cbc (trunk) to do what I wanted

Hello,
I would like to know if cbc currently supports row addition after a solve,
so as to cut the optimal solution and proceed to the next one. The purpose
is to find a series of close-to-optimal solutions, without solving the
whole ILP each time. Thanks in advance.
Cheers,
Pierre Le Bodic
