Judge Core

Or we should call it 'Judge Utils'. This libray will provide various method, which will be needed in online-judge system.

Overview

See what we've got (or plan to do) currently:

a compiler which build target from given src to some place
a sandbox mainly based on rlimit and seccomp, helps you to spawn process safely
a monitor (or judger) with sandboxes, enables you to run single part of judge test_case (if you got everything needed for judge)

Currently we are using a very normal approach by just running the following command:

strace $program_path

It will be better if we have a strace runned executor.
