+ * Topological sort a list or array.
+ * A Topological sort is used when you have a partial ordering expressed as
+ * 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.
+ *
+ * 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.
