 The functors provided in this package for constructing cones and cone-based spanners
-all have a template parameter `ConeBasedSpannerTraits_2`. To specify the requirements
-for the models (i.e., the various kernels from CGAL) that can be passed to 
-this parameter, we document a concept also called
-`ConeBasedSpannerTraits_2` here. Basically, this concept 
-specifies all the types and primitives (predicates and construction objects) that 
-the model should include to make the functors work properly.

 It is recommended that if you want to construct the cones or the cone-based spanners
 exactly, you should use the kernel `CGAL::Exact_predicates_exact_constructions_kernel_with_root_of`;
 and if you want to construct them inexactly, you should use the kernel
