/* chainDb.h was originally generated by the autoSql program, which also 
 * generated chainDb.c and chainDb.sql.  This header links the database and
 * the RAM representation of objects. 
 *
 * Note that this was built after the 'chainBlock' routine, which
 * was developed around a flat .chain file which is structured
 * fairly differently than the database table.   However this
 * module does refer to the same chain structure as is in chainBlock.*/
