> Driver is now cut down to it's minimal size by extracting all of it's sub
> tasks to separate classes. The rest should be cleaned up by
> * moving out some smaller parts of the code to sub task and utility classes
> wherever it is still possible
> * cut large functions to meaningful and manageable parts
> * re-order the functions to follow the order of processing
> * fix checkstyle issues
