The code object

The content (i.e code/docs) for the selected object. If the user provided a bare code object, it returns the source. If the user provided the `-i` or `-o` switches, it returns the selected input/output lines joined as a string. If the user used `-d CODE_OBJECT` it returns the docs for that code object.

The line range passed to `--lines`, converted to a 0-indexed range.
