+%%% Purpose : A priority queue.
+%%%----------------------------------------------------------------------
+%%% This module implements a priority queue as defined in 
+%%% "Priority Queues and the STL" by Mark Nelson in Dr.Dobb's Journal, Jan 1996
+%%% see http://web2.airmail.net/markn/articles/pq_stl/priority.htm for more
+%%% information. (A heap implementation is planned aswell)
+%%%----------------------------------------------------------------------
+%%% The items of the queue is kept priority sorted, and because of that,
+%%% a push() operation costs more than a pop() operation (wich only
+%%% needs to return the top item of the queue(read: list)).
+%%%----------------------------------------------------------------------
+%%% The priority queue can be deceptively nice to use when creating for
+%%% example a Huffman coding tree.
+%%% See http://web2.airmail.net/markn/articles/pq_stl/priority.htm or
+%%% Dr.Dobb's Journal Jan, 96 for more information on this.
