//! This example uses the BezierStar struct to create a profile and a path
//! for the Polyhedron::sweep function. Both of the stars are the same shape
//! but the path is ten times larger than the profile. The profile is swept
//! along the path, spinning seven times along the way.
//!
//! The output_viewer boolean controls whether we output the view of the curves
//! or the shape created by the sweep. Outputting the shape will most likely stall
//! OpenSCAD for several minutes.
//!
//! We use two Viewer(s) in this example so we can have different sized points and
//! lines.
