[Couenne] Creating Couenne problem directly in C++ code

[Stefan Vigerske]

Hi,

as far as I know, the CouenneOSInterface is working.
Next to AMPL and OS, also the link from GAMS to Couenne is available in 
code: 
https://projects.coin-or.org/GAMSlinks/browser/trunk/GAMSlinks/src/SolverInterfaces/GamsCouenne.cpp
