Implement getEqualVectorBasedOnPoint(Vector x, Point point)

Say we have a vector u = (1, 1) which can be expressed using points u = AB where A(0, 0) and B(1, 1). If we take a point P(2, 0) as a starting point then we can get another equal vector v = PQ whose tail is the point P(2, 0) and the head is Q(3, 1). So we have ||u|| = ||v|| and u is codirectional with v. Both vectors are equal free vectors.
