Doyle spirals, Doyle flower

Okay, the confusion between Javascript arrays, numarrays, pointarrays, and passed root values is sorted out:-)
There is no problem with the number of decimal places. The previous numarrays and pointarrays were programmed incorrectly.

Edit: Attached is a functional DoyleCell node. With helper nodes, the 3 basic circles of the spiral are drawn.
Place doylecell.js and doylefn.js in the nodeeditor extension directory. doylefn.js is not "linked" or "included", but its function is somehow found by nodeeditor.

Next up:
Complex number power math with ptA and ptB, to draw a spiral. Inward and outward circles.
Color/Style gradients.
Double Doyle spiral with two attractors, with moebius transform. (easy...really).
Log curves.
A double slider for p and q. Previous (brief) efforts resulted in failure of mouse to grab one slider.
Spheres will work instead of circles.
Edit multi-page Doyle Spiral pdf again, with derivation of Jos Leys equations.
Might try to get my 27 ratio equations, 18 of which are partial derivatives, to work. (not needed, but there is no license for Robin Houston code AFAIK,
just a message to have fun...)

New nodes could be created, or Macros may be able to do the work...
Might need some complex number math nodes.
