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)
• a judge_builder (WIP) to provide a higher level interface to start a judge, supposing the judge directory structure is following ICPC Problem Package format
