There was a problem hiding this comment.
looks good to me, I actually thought you will create a new error type instead of using EngineError, because architecturally speaking, the solver should not depend on the engine, because the engine will naturally depend on the solver and you do not want cyclic dependencies. (Makes sense right?) But I can refactor that.

Ah ok I misunderstood you then. Yes of course that makes sense thanks for taking care of that. |

Solver now times out after a certain amount of time has passed. Timeouts are now handled like other errors.
Closes #74.
