Corrected error in code.
Not at all clear where the symmetry planes and rotation axi are, so:
Running the script 12 times, with zeta and eta equations modified, produces all 12 patches.
Should modify the script to run once, and write all 12 csv files.
Or figure out symmetry and rotation, maybe in a node...

Increased density of input domain to 41 curves, 100 points per curve.
Running one patch, 4100 points, only takes a few seconds.

Eventually will try to open MoI4 from Python, and pass output 3D CSV and run ImportPointNetwork???
