  void clearSql()

===== Description =====
The method ''clearSql()'' empties entries from the SQL logging table earlier than the current timestamp. This allows the log to be cleared while the logging system is still in use.  

===== Known Issues =====
Because the method uses a 'delete from' methodology, and that the logging system may accumulated substantial volumes of data

  * The command may time out if run in a browser
  * The command may place the system under a heavy load, and there may be transactional timeout issues on some DBMS

An alternative methodology is:

  - Stop the logging system
  - Use a 'truncate table' command
  - restart the logging system
