code: total refactor

[emzinnia]

Whew, so there's a lot to go through here:

• [x] Switch data.[subject].ts to data/subject.ts or data/subject/index.ts and do this for all files
• [x] Use import { Foo } from './foo' syntax for all files
• [ ] Upgrade to [email protected]
  • [ ] Use stylus-loader for styles
• [x] Update any config files -- tslint, tsconfig
• [x] Set up structure for tests
• [ ] Set up auto-lint, auto-test git hooks / prepublish scripts
