This logic is from the curve sundivide node, used to add points with proper handles in between two existing points. However, the same logic is used for trimming of Bezier splines, and possibly interactive point insertion in the future, so it's helpful as a general utility. The logic is converted to depend on a bezier spline instead of being static. A temporary segment spline can be used for the latter use case.
