 From leda_graph.hpp:

class out_edge_iterator
       : public iterator_facade<out_edge_iterator,
                                const leda::edge&,
                                const leda::edge*>

Can someone explain to me the parameter "const leda::edge*"?
says the last template parameter is the type for the difference between
two iterators, how can this be a pointer?

Shouldn't it just be the default std::ptr_diff_t?
