I think we either should keep these for convenient debugging or remove everything from line 262 and down.

This comment and its answers reflects the possible need to have simple debugging features of dic2owl and how this may be achieved.

To me there are two things here: Unit testing and debugging.
I want to add some unit tests that check the generation is executed as would be expected. At the same time, it might be nice to return some central variable values during development.
