## Describe your changes
Add a .gitattributes file with `* text=auto` so that file endings are
automatically handled by git and overrides the user settings.
Otherwise, if a user hasn't set `git config core.autocrlf` a file saved
on Windows uses CRLF endings. This shows up as the whole file being
changed.
