Parameters
- centre: Point
  Helix central origin column.
- start_radius: number
  Base radius.
- end_radius: number
  Top radius (permits conical helices).
- start_angle: number
  Entry angle.
- n_turns: number
  Number of vertical rotations.
- pitch_z: number
  Height gained per full turn.
- segments: number
  Resolution of the helix.
- cw: boolean = false
  True for clockwise.
Returns Point[]
Array of Points traversing up the Z axis in a helical spiral.
