v0.0.1

This isn't really a release, but more or less a tiny milestone before merging large change set.

• passed all tests (under tests directory)
• built musl libc and glibc successfully, with an overhead of 2x (musl: 9s -> 18s)
• ran complex programs (such as firefox/chrome) without crashing

Keep in mind the tool little to no functionality, so there could be regressions after tools got fleshed out.
