docstring: Tries to guess the extension.
  
  The mime type is passed to each registered mime type guesser in reverse order
  of their registration (last registered is queried first). Once a guesser
  returns a value that is not NULL, this method terminates and returns the
  value.
  
  @param string $mimeType The mime type
  
  @return string The guessed extension or NULL, if none could be guessed
