This is a very basic csv parser. It needs a lot more work to be a real CSV parser, but it is all I need.
CSV.parse(string, separator \\ ",", quote_char \\ "\"", skip_lines \\ 0)
where string is a binary. CSV.parse/1 will return an array of rows for the CSV in string where separator is used ans the field separator and quote_char is the quote char. Each row is a list of strings in each field. skip_lines is the number of lines to skip before adding rows to the results. Use this to skip headers.
CSV.parse_file(filename, separator \\ ",", quote_char \\ "\"", skip_lines \\ 0)
reads the file named filename and then parses the contents of the file using parse.
This code only handles UNIX or MS-DOS newlines. It will fail on old MacOS '\r' newlines.
