Description
The current TableFileParser cannot read strings that contain any line-breaks. Instead, the line-break is interpreted as a new data-row.
To be able to distinguish between a string-column line-break and a data row line-break, the TableFileParser must also support string-quotation.

Alglib read_csv does not support the functionality.
escaped fields (ones in double quotes) are not supported
Note: See
TracTickets for help on using
tickets.
Maybe we should use the parsing functionality available in the newer alglib version.
