Remove useless utility class.
Rename main class to match the project name.
Completely rewrite the configuration handling. The previous implementation ignored the properties file in the project directory, plus it used hundreds of lines of code to implement what Java already does for free.
Remove useless code and unsafe setters which replace the entire database or column models.
Delete interface which was never used.
Simpler loop implementation which is clearer to read.
Remove hexutil class since we have a perfectly good conversion tool from Apache which is already optimised and properly tested under a wide variety of conditions.
