      :param str uuid: UUID to format
      :param int max_length: Maximum length of result string (> 3)

      This function formats a UUID so it is not longer than *max_length*
      characters. The resulting string is returned. It does so by replacing
      characters at the end of the *uuid* with three dots, if necessary.
      The idea is that the start of the *uuid* is the most important part
      to be able to identify the related entity.
  
      The default *max_length* is 10, which will result in a string
      containing the first 7 characters of the *uuid* passed in. Most of
      the time, such a string is still unique within a collection of UUIDs.
