A class for generating an icosahedron geometry.
radius — Default is 1.
detail — Default is 0. Setting this to a value greater than 0 adds more vertices making it no longer an icosahedron. When detail is greater than 1, it's effectively a sphere.
An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
