Formatter

[justinmchase]

• Opinionated, no formatting parameters available
• Can be run in check mode, which makes no changes but emits errors if there are differences
• Comments must be preserved
• Reads any file, parses it to ast, re-generates code from that ast
  • in check mode, diff the two generate errors
  • in non-check mode write the formatted version back to disk

Its possible a generic formatter parser will need to be written which knows how to parse blocked code and pay attention to line endings and preserve comments. It would be a language agnostic formatter, not sure if thats actually possible or if we just need to make the full parser aware of whitespace and comments.
