[Cbc] SOS max type number ?

[ycollet at freesurf.fr]

Hello,

What is the max SOS type number supported ?
If I looked in the code, there is an assert:
   assert (sosType_>0&&sosType_<3);
Which seems to tell that only SOS1 and SOS2 are supported.
But if you send sosType_ = 3 via the constructor, nothing happens, but  
the results is the results obtained via the SOS2 model.
