The example notebook uses the directory test-data to hold both the allowed-languages.txt file and the files generated while running the notebook. This makes it hard to start over. In general, the convention is to have the test-data directory as read only. So the ask is

1. Put the files generated while running the notebook somewhere else. .../examples/tempdir or something is fine.
2. Add the the make clean target the removal of the intermediate files.
