--  Description:     Converts CSV (text with Comma Separated Values) input
--                   into LaTeX array output. NB: the special characters
--                   like '%', '\', '&', '{',... should be translated before!
--                   CSV is "the" ASCII format for Lotus 1-2-3 and MS Excel
