Hello,

I'm wondering if there's a straightforward way to modify the arrangement 
structure on a sphere such that the vertices/edges in the arrangement have 
additional information from the curves that are used to create them. 
Essentially I am looking to add annotations to the arrangement.

I would like to replace Curve_2 with a structure that has an annotation 
(e.g., a label) and have vertices/edges in the arrangement keep a list of the 
labels of the curves that pass through them, but I don't know if there is 
already a clear way to do this.

Thanks,
Evan
