Using thornton cutters and measurments

You can adjust the teeth height with the head parameter and the root can be adjusted with the clearence parameter.
The formulas used can be found here: https://github.com/looooo/freecad.gears/blob/master/pygears/cycloid_tooth.py#L39
and here: https://github.com/looooo/freecad.gears/blob/master/pygears/cycloid_tooth.py#L40

Still working from Z=100 and M=0,8
See the formula's of Thornton. With all due respect. If I calculate the Outside diameter (Da) from the formula in the source with a head off zero I get 82,4.. If I make a techdraw, the outside is over the teeth is 81,7. So somewhere it's going wrong. Not that it's a big issue. I can manualy change the measurements. But it would be great if I understand if I'm doing something wrong or the code :-).
