Constructs an arbitrary regular star polygon (a generalization of the regular polygons).
The polygon is enclosed by a regular polygon with @racket[side-count] sides each
@racket[side-length] long. The polygon is actually constructed by going from vertex to
vertex around the regular polgon, but skipping over every @racket[step-count] vertices.
vertex around the regular polgon, but connecting every @racket[step-count]-th vertex
(i.e., skipping every @racket[(- step-count 1)] verticies).
For examples, if @racket[side-count] is @racket[5] and @racket[step-count] is @racket[2],
For example, if @racket[side-count] is @racket[5] and @racket[step-count] is @racket[2],
then this function produces a shape just like @racket[star].
