- Fix hocr-combine: Delete the function call to `importNode` which does not exists in `etree` and seems not necessary anymore.
- Fix hocr-eval: The function `get_text` of this file failed in Python 3 and we use now the same code of this function as in the other tools.
- Fix hocr-lines: It was outputting byte strings in Python 3.
- Add tests for hocr-combine, hocr-eval, hocr-eval-geom, hocr-lines
