Regular star polygons are equilateral equiangular polygons, created by connecting one vertex of a simple,
regular, [math]N[/math]-sided polygon to another, non-adjacent vertex and continuing the process
until the original vertex is reached again.
Parameter [math]Step[/math] means that we connect every [math]Step[/math]-th points,
so for [math]Step = 1[/math] every point is connected to the next,
for [math]Step = 2[/math] - to the next nearest etc.
