Use the golden spiral method to generate evenly spaced points on a cylinder.
The "golden" part is derived from the golden ratio; stand at the center, turn a golden ratio of whole turns, then emit a point in that direction.
Points are generated starting from the bottom of the cylinder, ending at the top. Contiguous entries in `Points_ generally will not be spatially adjacent.
Points_ to append to.
Origin is the bottommost point of the cylinder. `Axis is the orientation of the cylinder. Radius_ is the radius of the cylinder.
Height is the height of the cylinder. `NumPoints is the number of points to generate. IncludeEndCaps_ determines whether or not points are generated on the end caps of the cylinder.
SpiralSeed is the starting index for golden spiral generation. When using this method to continue a spiral started elsewhere, `SpiralSeed should equal the number of particles already created.
