*
* Main differences between implementations are underlying max-flow algorithm and graph type (i.e. results are the same, performance differs).
*
* For activating MAXFLOW software, define CGAL_USE_BOYKOV_KOLMOGOROV_MAXFLOW_SOFTWARE. It activates Alpha_expansion_graph_cut_boykov_kolmogorov,
* and makes CGAL::internal::Surface_mesh_segmentation choose this implementation for graph-cut.
* By default, we use MAXFLOW and the class Alpha_expansion_graph_cut_boykov_kolmogorov.
* For deactivating MAXFLOW software and using boost implementation instead, define CGAL_DO_NOT_USE_BOYKOV_KOLMOGOROV_MAXFLOW_SOFTWARE.
* It deactivates Alpha_expansion_graph_cut_boykov_kolmogorov, activate boost versions
* and makes CGAL::internal::Surface_mesh_segmentation using Alpha_expansion_graph_cut_boost
* as default implementation for the graph-cut.
*
* Also algorithms can be used by their-own for applying alpha-expansion graph-cut on any graph.
