C# Class Kajabity.Tools.Csv.CsvReader

This class reads CSV formatted data from an input stream. It can read individual fields in a row, a full row or the whole file. Data can only be read once - so if the first field in a row is read, it won't be part of the row if that is read next. The term Row is used rather than line because quoted fields can include line breaks (real, not escaped) so that one row may be spread across multiple lines.
