Finds the closes line between 2 line segments, were the magnitude of u, v are the lengths of each segment L1 = P(s) = p0 + s * u, where s is time and p0 is the start of the line L2 = Q(t) = q0 + t * v, where t is time and q0 is the start of the line
Point where L1 begins
Direction and length of L1
Point were L2 begins
Direction and length of L2
