Macro polyhedron 

macro_rules! polyhedron {
    (points=$points:expr, faces=$faces:expr, convexity=$convexity:expr) => { ... };
    ($points:expr, $faces:expr, $convexity:expr) => { ... };

Creates a polyhedron.

#params

points: The vertices of the polyhedron.

faces: A list of lists of indices into points.

convexity: The number of outside faces a ray intersecting the polyhedron might encounter. Preview only.

expansion: A Scad struct literal.
