[Cbc] Cut Generation

[Ted Ralphs]

Depending on exactly what the purpose of generating these cuts is, you
might also take a look at

https://github.com/tkralphs/CuPPy

This is a very simple GMI generator in Python that gets the optimal tableau
from Clp via the Python bindings provided by CyLP and generates the
corresponding GMI cuts. It is intended mainly for instructional
purposes---it would be very slow and also not very sophisticated in
practice. It can, however, animate the cut generation procedure for 2D
examples using. I use it for teaching purposes.
