[Bonmin] Python wrappers for BONMIN?

[Stefan Vigerske]

Hi,

you could also look into a problem library like MINLPLib 
(http://www.gamsworld.org/minlp/minlplib/minlpstat.htm).
There are also small instances (<10 variables) that should be easy 
program in python.

One should take a bit care of picking only convex instances, so that the 
test outcome is reliable.
