Updated Alpha.
Flow now works.
Cleanup removal of old powerCone & powerConeSpiral has not been done. Preliminary code is shown, but still needs some help. Need to include some Chain script like cleanup code.
Cleanup on Cancel has not been done. No more time today.

Speed may be too slow for sliders? The mathematica sliders were also slow.
It may be faster to do one cross section and scale it ???

One peculiarity with using build presets, is that during one session of MoI,
Changing a parameter, such as "closed" checkbox, exiting script, and right mouse click to re-run script, causes the changed checkbox setting
to revert to its preset. It only took a couple of hours to realize this simple fact :-)

ps, If the user does not like the tip, an iso-line can cut the tip off. And then blendCap can add a new tip.
Also, Inner Flat has not been finished.
