[Cbc] SOS question

[ycollet at freesurf.fr]

OK, thanks for your answer.
I'm now stuck in the C++ part of the SOS thing.
So, if the SOS type is 1, we leave the variables used in the SOS set  
to binary.
If SOS type > 1 then we remove the binary flag of the variables used  
in the SOS set ?

Am I right ?
