CbcBranchCut.cpp prints without log level check

I feel like it's important for a library to have the feature to disable all kinds of logs in case of user has dependency on stdout.

I certainly agree with you and this is undoubtedly a mistake. It would be helpful if you could paste in the messages that are printed without log level check. This would make it easy to find and fix them.

Example:
CUT down Row cut has 2 elements with upper rhs of -1
1 * x0 -1 * x1

Was able to find it in CbcCutBranchingObject::branch()
