+ * Topological sort a list or array.

+ * dependencies between elements (also often represented as edges in a directed 
+ * acyclic graph).  A Topological sort should not be used when you have a total
+ * ordering expressed as a {@link Comparator} over the items. The algorithm has 
+ * the additional characteristic that dependency sets are sorted by the original 
+ * list order so that order is preserved when possible.</p>
+ * <p>
+ * The sort algorithm works by recursively visiting every item, once and
+ * only once. On each visit, the items dependencies are first visited and then the  
+ * item is added to the sorted list.  Thus the algorithm ensures that dependency 
+ * items are always added before dependent items.</p>
