some draw contour edges instead of relying on vertex drawing

error fixing  but broke other parts
attempting to sleuth out bug where closed loop fails
bug with mainting a reference to actual class data instead of copying it :-/ Iteratively increased

vertices with each draw.  Whoops!

Now able to insert cuts between others (hassle)
Delete cut lines with right click
Move cut line on and off object no errors
no errors with no intersection
max number of segements per ring constrained to 1/2 total cross section verts of first slice
