class Spring

Description:
	A physical model of a spring, useful in many applications. Properties only evaluate
	upon index making this model good for lazy applications

API:
	Spring = Spring.new(number position)
		Creates a new spring in 1D
	Spring = Spring.new(Vector3 position)
		Creates a new spring in 3D

	Spring.Position
		Returns the current position
	Spring.Velocity
		Returns the current velocity
	Spring.Target
		Returns the target
	Spring.Damper
		Returns the damper
	Spring.Speed
		Returns the speed

	Spring.Target = number/Vector3
		Sets the target
	Spring.Position = number/Vector3
		Sets the position
	Spring.Velocity = number/Vector3
		Sets the velocity
	Spring.Damper = number [0, 1]
		Sets the spring damper, defaults to 1
	Spring.Speed = number [0, infinity)
		Sets the spring speed, defaults to 1

	Spring:TimeSkip(number DeltaTime)
		Instantly skips the spring forwards by that amount of now
	Spring:Impulse(number/Vector3 velocity)
		Impulses the spring, increasing velocity by the amount given
