+/**
+ * @page visited_counters Visited Counters
+ * A visited counter is an alternative to a visited flag for elements of a
+ * graph datastructure.
+ * A visited counter is an integer number added to the elements of a graph.
+ * There is also a global reference number for the whole datastructure. It is
+ * now possible to mark nodes by setting their visited counter to the global
+ * reference counter. Testing is done by comparing with the global reference
+ * counter.
+ * The advantage to simple boolean flag variables is that you can clear all
+ * element marks by increasing the global reference counter and don't need to
+ * visit the whole structure.
+ * This makes it more efficient when you only visit/mark a small amount of
+ * nodes in the graph.
