docs: Serialize an Xmrs object to a SimpleMRS representation
  
      Args:
          ms: an iterator of Xmrs objects to serialize (unless the
              *single* option is `True`)
          single: if `True`, treat *ms* as a single Xmrs object instead
              of as an iterator
          properties: if `False`, suppress variable properties
          pretty_print: if `True`, add newlines and indentation
          color: if `True`, colorize the output with ANSI color codes
      Returns:
          a SimpleMrs string representation of a corpus of Xmrs
