> The Driver class contains ~600 lines of code responsible for executing the
> command. That means that from the Query Plan as input the appropriate tasks
> should be executed. This is a thing done by the execute function, which is
> ~300 lines long, and also has some sub functions to help this task. All these
> codes should be put into a separate class, where it can do it's job without
> getting mixed with the other codes in the Driver.
