Roadmap

• [x] First dev release (default browser profile only, single-file input)
• [x] Release as package on NPM
• [ ] Allow .cansei.json to mark CSS properties as "ignore", "warn" or "error".
• [ ] Browser profile generation using Google Analytics (OAuth)
• [ ] Multiple file support (globbing, show filenames in output)
• [ ] LESS/SCSS support?
• [ ] Hound integration or separate service?
