	CFrame.rightVector describes the vector that points to the right of a CFrame
	So the left most point we can have is midPoint - CFrame.rightVector * range
	And the right most point we can have is the opposite
	Lerp lerps a vector from a to b based on an alpha(0-1)
	So we then lerp from the left to right most by a random value between 0 and 1, to find a random position between the left and right most points
