I think you should add PID to the log filename to help differentiate when running multiprocess, or just running same binary over and over.

Also maybe we could/should consider a third-party dependency for this: https://github.com/gabime/spdlog

@davidbeckingsale Does it work to open an issue for this? I intended this to be a very basic commit that just introduces the functionality to move from monitor printouts to a file, even if overwritten. This still serves the use-case of manual. visual inspecting where we run one compilation/execution and want to see the output.

@davidbeckingsale I wasn't aware of spdlog and it looks awesome! However, I'd like to keep dependencies to a minimum until we have a robust, well-integrated core. Can we again open an issue for forward development?
