51     This DataListSource child class gets the data from a
52     CSV (comma seperated values) file on disk.
53     <BR>
54     The CSV MUST have a 'header' line before any data.
55     The 'header' line is a CSV line that provides a name
56     for each column of data in the file.
57    
58     All lines that start with '#' or '//' are ignored as
59     comments.
