Massive update. Changed many method signatures, added and removed many methods. Trasaction support changed completely. Added SAVEPOINT support. Now all querying method doesn't use transaction at all.
Changed behaviors of  method. And deleted error-returning version. Now the method throws exception for errors on transaction command itself.
Fixed bug of `-checkIntegrity` method.
Added block-based transaction method returning object value.
Adding error argument considered, but disposed because error of transaction command itself it critical, and shouldn't be raised. The error is not regular situation. So it still be an exception.
