add debugging functionality

[EnnoMeijers]

Currently running ld-workbench against large files is a pass or fail process. It would be very practical to have additional options for debugging for example process the a specified number of iterator results or log intermediate results to the console.

Good idea to add some more debugging.

or example process the a specified number of iterator results or log intermediate results to the console.

I don’t understand this sentence. There’s already a spinner that shows intermediate counts. Would you like to output the contents of all processed statements to the console?

I could imagine to have a verbose option like in other tools that shows the result of the transformation in the console. This would be really helpful. Next to that it would be nice to have an option (or config setting) that says process only the first n iterations, write the output to file and then quit.
