### FUNCTION

  Checks collision for a hexahedron and a sphere.

### EXAMPLE

  Hexahedron (box) and sphere (sphere) collision checking.

      NJS_BOX box;
      NJS_SPHERE sphere;

      box.v[0].x = -150.f; box.v[0].y =  100.f; box.v[0].z =  100;
      box.v[1].x = -150.f; box.v[1].y =  100.f; box.v[1].z = -100;
      box.v[2].x =   50.f; box.v[2].y =  100.f; box.v[2].z = -100;
      box.v[3].x =   50.f; box.v[3].y =  100.f; box.v[3].z =  100;
      box.v[4].x = -150.f; box.v[4].y = -100.f; box.v[4].z =  100;
      box.v[5].x = -150.f; box.v[5].y = -100.f; box.v[5].z = -100;
      box.v[6].x =   50.f; box.v[6].y = -100.f; box.v[6].z = -100;
      box.v[7].x =   50.f; box.v[7].y = -100.f; box.v[7].z =  100;

      sphere.c.x = 100.f;
      sphere.c.y =   0.f;
      sphere.c.z =   0.f;
      sphere.r   = 100.f;

      njCollisionCheckBS(&box, &sphere);

      Result
      Return value: 1

### NOTES

  NJS_BOX structure(box type)

      typedef struct{
          NJS_POINT3 v[8]; /* vertex list for hexahedron */
      } NJS_BOX;

  Corresponding vertices with vertex list index

  NJS_SPHERE structure(sphere)

      typedef struct{
          NJS_POINT3 c;/* center of the sphere */
          Float      r;/* radius of the sphere */
      } NJS_SPHERE;

  A sphere consists of center coordinate c and radius r.
