/** Translate cell function keywords.

    This class provides a convenient way to translate a string keyword used as
    a cell function argument.  Since Calc's built-in cell functions don't
    localize string keywords, this class is used mainly to deal with an Excel
    document where string names may be localized.

    To use, simply call the

       ScCellKeywordTranslator::transKeyword(...)

    function.

    Note that when the locale and/or the opcode is specified, the function
    tries to find a string with matching locale and/or opcode. But when it
    fails to find one that satisfies the specified locale and/or opcode, it
    returns a translated string with non-matching locale and/or opcode if
    available. */
