void vpSpring::Connect	(	vpBody *	B0,
		vpBody *	B1,
		const Vec3 &	p0,
		const Vec3 &	p1
	)

connect bodies B0 and B1 with the spring.

Parameters:

	p0	a position of the spring attached to B0. It is represented in a body fixed frame of B0.
	p1	a position of the spring attached to B1. It is represented in a body fixed frame of B1.
