This node is quite similar to the curve to points node, but creates points for only the start and end of each spline. This is a separate node because the sampling from the curve to points node don't apply, and just for ease of use. All attributes from the curves are copied, including the data for instancing: tangents, normals, and the derived rotations. One simple use case is to make round caps on curves by instancinghalves of a sphere on each end of the splines. Differential Revision: https://developer.blender.org/D11719
