 * \class COMET::IDbiOutRowStream
 *
 *
 * \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 COMET::for IDbiSqlValPacket. Its
 *  primary purpose is to provide an << operator with built-type
 *  checking to simplify the writing of IDbiTableRow subclasses.
