the last chapter is about other splines! and so I've been calling it "the extended family", but for some reason I really don't like the name, it feels, negative, to me

the tricky thing is that calling it "other splines" sounds too miscellaneous for a whole chapter, and calling it "cubic splines" makes it seem like we haven't been talking about a cubic spline up until that point
so, idk!

going for The Extended Universe
