[Scip] Gomory cuts

[Kati Wolter]

Hey James.

In order to answer your question, it would be good to have a few more
details:

- Which parameters did you change to achieve your goal?
- Are you using SCIP as standalone solver or as a framework with you own
plug-ins, like new cutting plane separators or constraint handlers?

Best regards,
Kati
