"surfaceNormals" node

Outputs the normals of the surfaces in 2 methods.
method 1: Faster, better flow ==> by using normal output
method 2: Slower, more reliable ==> by using "Dir" and "Base" outputs
"Dir" and "Base" can match with "vector/LinebyVec" node and "Points2/GetCrvSFrame" node to generate normals.




inputs:
surface/surfaces
u and v divisions

outputs:
Dir: direction of the normal.
Base: points on the surface.
Normal: surface normals

address:
Points/SurfaceNormals

updates :
Unified Normals option added
Rebuild Surface option added
Invert mode added
Small improvements :)
