 I think one of the biggest things missing from DIP – especially for
 generic MILP is a presolve and postsolve. This is one place you or a
 student of yours could make a huge contribution. By figuring out a “clean”
 API for doing IP presolve via CBC? CoinUtils? Cgl? and the corresponding
 postsolve on a model before handing it to DIP….

 You mentioned some student (not Lehigh) that wanted to help out. That
 would be a major contribution.
