[Bf-blender-npr] normal-edit modifier

[Vicente]

Hi again Bastien,

Sorry for the delay in the answer.
Yes, I agree that something can be done following those instructions. 
However I'm still not completely happy. So I'm thinking of doing myself 
a python clone of the softimage approach. Do you know if the python API 
is good enough to achieve that result(the shown in the video)? In other 
words, Can I edit the normals of a mesh using python?

Thanks

Vicente
