* @author Inscrutabilis /
* Generates a geodesic sphere geometry
* By default, it is 1x1x1 octahedron, as a first approximation to sphere
* It will return more sphere-like object if you specify iterations > 0
* But please keep in mind that it generates (4 ^ iterations) * 8 faces
* Radius argument overrides default sphere radius (1)
