Doyle spirals, Doyle flower

Using more "ported" code, the Doyle spiral of circles is being formed, but only one arm.
I think that the arms are being calculated, but only the last arm survives.
Saving by .concat of pointarray and .concat of radii numarray, or .push do not seem to work...maybe xlength needs to be set?
So it is back to debugging:-)
