Very useful tool.

Just a quick question, is there a way to setup a callback function, central to all supported solvers, to monitor progress and interrupt when necessary by having the callback function return a nonzero value, e.g. (a) when a time limit has been reached, (b) when a certain quality of solution is achieved (MIPgap<eps)) (c) etc.. I know how to do all this with Cplex API but not over OSI. I was hoping LP could offer a solution.
