Jane Tournois 47a5606eea this commit fixes the following issue : ... <<The AABB_tree<AT> internally use the spatial searching and in particular instantiates Search_traits_3 with AT. This implies according to that page that the concept AABBTraits must be a Kernel. A clean solution is adding a new concept in Spatial searching that describes requirements of the template parameter of Search_traits_3. Then we can say that AABBTraits refines this concept. For consistency, we do the same for the template parameter of Search_traits_2. >>		2016-08-23 16:28:50 +02:00
