[Cbc] refusing feasible solutions

[Pietro Belotti]

John,

apologies for the late reply. I am looking at the Bonmin code to see where 
the solvercharacteristics makes a difference. As for the virtual function, 
I guess I overlooked some library version and posted the wrong problem: 
now, declaring a virtual CbcModel::checkSolution() allows me to perform my 
own check in my model class, and Cbc uses only the accepted solutions as 
valid. It would then be desirable to have that function virtual in the 
repository.

Thank you very much,
Pietro
