Detailed Description

A wheel is a body that consists of n points laid out in a circle to form the circumference, and a central point acting as a hub. The points on the circumference are evenly spaced and each is connected to the next in a circle. All points on the circumference are connected to the hub. This is more like an n-gon than a wheel, but the presence of the hub makes it seem more wheel-like. It certainly rolls like a wheel and if I want to call it a wheel, I can, dammit.

Vector2  v 
)

Make a cross-braced wheel of points connected by springs to a central hub.

Parameters
nNumber of sides.
rRadius.
sCoefficient of restitution of the springs.
vLocation of center.
Returns
Pointer to a point on the wheel.
