Create a plane that is oriented perpendicular to one end of a selected curve/spline?

This seems like it should be very simple because it is built in to OnShape as the "Curve point" option when creating a plane manually. However, I cannot figure out how to do this in a featurescript. It would be optimal if you could just select a spline/line/polyline, and it would create a plane perpendicular to either of it's ends.

Forgive me if it is indeed simple as I am just starting to get into featurescripting.

    Our Plane feature (cplane.fs) uses evEdgeTangentLine to get a line tangent to the curve at a particular parameter (0 or 1 in this case) and then constructs a plane using its origin and normal. See here for a simplified example.
