-  // next() member functions make possible to iterate on the keys of the

   // For the proper functonality of this class, we should notify it

-  // as \e add(), \e erase(), \e build() and \e clear(). The \e add() and

-  // from the graph. If all items are erased from the graph or from an empty
-  // graph a new graph is builded then it can be signaled with the

+  // from the graph. If all items are erased from the graph or if a new graph

   // them from the container, on the other way on item addition we should
   // first extend the container and just after that signal the alteration.
