There seems to be some kind of bug with mPath_Array.
After running the script, without Apply, the CurvesU are selectable and deletable by MoI, the points are not selectable nor deletable by MoI, until Apply is clicked.

After clicking Apply and deleting everything in MoI, and returning focus to the nodeeditor canvas, Run does not produce any result, until an input wire, or output wire is detached and re-attached, or knob is "rotated." Also detaching and reattaching the gold wire from ConvertPts, point mode, causes the points to re-appear.
Detaching and reattaching the gold wire from convertPts, CurvesUmode, causes the lines to re-appear.

Also, highlighting of the CurvesU lines will reappear inappropriately.
