-/* Fibonacci heaps are somewhat complex, but, there's an article in
-   DDJ that explains them pretty well:
-
-   http://www.ddj.com/articles/1997/9701/9701o/9701o.htm?topic=algoritms
-
-   Introduction to algorithms by Corman and Rivest also goes over them.
-
-   The original paper that introduced them is "Fibonacci heaps and their
-   uses in improved network optimization algorithms" by Tarjan and
-   Fredman (JACM 34(3), July 1987).
-
-   Amortized and real worst case time for operations:
-
-   ExtractMin: O(lg n) amortized. O(n) worst case.
-   DecreaseKey: O(1) amortized.  O(lg n) worst case. 
-   Insert: O(2) amortized. O(1) actual.  
-   Union: O(1) amortized. O(1) actual.  */
