Taken from book Real Time Collision Detection, from Christer Ericson.

Parameters

pb	the closest point to the sphere center on the box surface
ps	when colliding, matches pb, which is inside the sphere. when not colliding, the closest point on the sphere
normal	direction of motion of the box

Returns: true if the distance is negative (the shape overlaps).
