[Scip] providing SCIP with a new current solution during BCP

[Ambros Gleixner]

Dear Hélène,

sorry for the long wait.  Let me ask back to make sure I have understood 
you correctly: Are the solutions S and S' you talk about solutions of 
the LP relaxation?  I.e., do you want to move to another LP solution on 
the optimal hyperplane?  Would this solution be basic and would you know 
the basis?

Best regards

Ambros
