Theorem fvtransport 29535
Description: Calculate the value of the TransportTo function. This function takes four points, A through D, where C and D are distinct. It then returns the point that extends C D by the length of A B. (Contributed by Scott Fenton, 18-Oct-2013.) (Revised by Mario Carneiro, 19-Apr-2014.)
