Removed the -i option.  The instance is now specified without an option.  The --db-name option can be used to specify an actual database name.
Remove temp db tables prior to dumping.  Added --no-db-cleanup option to inhibit this behavior.  No longer using -i option to execSql.sh
Modified comment with execSql.sh usage to remove -i option.
Removed -i from calls to execSql.sh.
