[MAINT] remove useless line in curvature_fit.py

hello,
In the curvature_fit.py function i notice one useless line :

line 35 if (i == 175):
print("Debug")
Moreover there are commented lines :
line23-24 . vertex_normals =
faces=
line 44 rotation_matrix =
line 53. neigh =
line 68 parameters =

It's a little confused to have commented lines that defines variable differently,
can we remove this lines ?

thanks for your help

Open curvature_fit.py and inspect the listed lines in the curvature-fitting function, especially the conditional Debug print and commented variable assignments. Remove the unused debug and commented lines, then verify that the function remains valid and contains no unintended references to those variables.
