It would be very useful to add contact normal into b2ContactBeginTouchEvent, like b2ContactHitEvent already has.

I need to implement the collision logic based on the collision normal. If my understanding is correct, currently I have to use b2Shape_GetContactData() and do a linear search for the targeted collision between A and B. Is there a more efficient method?
