 * \class TDbiOutRowStream
 *
 *
 * \brief
 * <b>Concept</b> Output stream for the values of a single table row
 *  with type checking and deferred sequence number asignment.
 *
 * \brief
 * <b>Purpose</b> This is a helper class for TDbiSqlValPacket. Its
 *  primary purpose is to provide an << operator with built-type
 *  checking to simplify the writing of TDbiTableRow subclasses.
