- in DistanceResult constructor, initialize nearestpoints and normal with
    NaN vectors,
  - in test_fcl_geometric_shapes.cpp, initialize plane with zero vectors.

  - this member stores the normal (direction object 2 should be translated by
    the penetration depth to make objects collision free) in case boths objects
    are in collision.

  - old constructor is deprecated.

  - security_margin is the distance below which collision test returns
    collision,
  - break_distance is the distance below which bounding boxes are broken
    down.

  - this feature is implemented in a more general way in HPP.

  This enables users to install the official version of fcl together with
  hpp-fcl.

  - add a Boolean value in CollisionRequest to trigger this option,
  - if selected, fcl::collision function will compute a lower bound
    on the distance between the two objects if they do not collide.
