- Add class level Javadoc documentation (I hope it's somewhat correct)
- Make fields private if possible
- Enable the trace option when running in standalone mode
- Instead of System.out.println(), use trace()
- Remove 'verbose' flag, use the trace flag instead
- Remove @Override so it can be compiled with JDK 5 (so that the nightly build works)
- Use { .. } even for single line blocks - this is the code convention used in H2 (so that insertion of a new line of code anywhere is always "safe")
