Callback

[dhendryc]

Add a callback to Boscia so the user has the option to implement custom behavior for stopping algorithm, reading extra information, do additional stuff etc.

it could be added to Bonobo as well, and then we would use the Bonobo callback to potentially interrupt, wrapping the user callback

I was thinking about that but I'm not sure it is enough.
This came up with the Network design problems and where we want some custom behavior in the evaluation of the node.

yes you can have the two separately:
the Bonobo callback would just decide whether to interrupt the BNB search. The user callback could change some options or decide some things in evaluate_node!
