  in GJKSolver_indep::shapeDistance<TriangleP, TriangleP>.

  triangles are in collision but distance between them is slightly positive.

  It seems that GJK fails when the triangles are close to each other but not
  colliding,
  Add a test in test_fcl_gjk with specific triangles and transforms that make
  GJK fail.

  - Collision detection calls distance computation and returns collision
    if the distance between objects is below the security margin.
  - This modification requires a modification in the structure of the software
    to make collision detection and distance computation closer.
  - GJKSolver_indep::shapeTriangleDistance and
    GJKSolver_indep::shapeTriangleIntersect have been replaced by
    GJKSolver_indep::shapeTriangleInteraction.

  instead of -1.
