Solver-Callback handling protos:
Callback functions allow for a fine-grain control, and ongoing interaction
with the solver during the solve process. The overall architecture is that
upon solve invocation the user will select what type of interactions to have
with the solver, and whenever the solver offers an interaction enabled by the
user, return the statistics collected up to that point, and any additional
information required by the user. Once done, the callback function must
return a message to the solver to continue with the solve process.
