+/**  
+ * \brief a Candidate Queue used in static routing.
+ *
+ * The CandidateQueue is used in the OSPF shortest path computations.  It
+ * is a priority queue used to store candidates for the shortest path to a
+ * given network.  
+ *
+ * The queue holds Shortest Path First Vertex pointers and orders them
+ * according to the lowest value of the field m_distanceFromRoot.  Remaining
+ * vertices are ordered according to increasing distance.  This implements a
+ * priority queue.
+ *
+ * Although a STL priority_queue almost does what we want, the requirement
+ * for a Find () operation, the dynamic nature of the data and the derived
+ * requirement for a Reorder () operation led us to implement this simple 
+ * enhanced priority queue.
