        - Reduced the object overhead in PreparedStatement by reusing the same
          StringBuffer object throughout. Similarly SimpleDateStamp's are alse
          reused in a thread save manner.
        - Implemented in PreparedStatement: setNull(), setDate/Time/Timestamp
          using Calendar, setBlob(), setCharacterStream()
        - Clob's are now implemented in ResultSet & PreparedStatement!
        - Implemented a lot of DatabaseMetaData & ResultSetMetaData methods.
          We have about 18 unimplemented methods left in JDBC2 at the current
          time.
