    Takes care to avoid illegal characters, reserved file names, ambiguity between
    upper- and lower-case characters, and clashes with existing files.

    Args:
            userName (str): The input file name.
            existing: A case-insensitive list of all existing file names.
            prefix: Prefix to be prepended to the file name.
            suffix: Suffix to be appended to the file name.

    Returns:
            A suitable filename.

    Raises:
            NameTranslationError: If no suitable name could be generated.

    Examples::

            >>> userNameToFileName("a") == "a"
            True
            >>> userNameToFileName("A") == "A_"
