When using npm start and then something like http://localhost:4001/?url=path/to/file.xml, the assets for file.xml are not loaded because the URLs are not made relative to the file's location. It would be nice to fix that.
Add CLI option
It would be convenient to have something like npm start path/to/file.xml work.
Some stray thoughts on potential improvements.
