-    Analyzes tight feedback in a design.
+    Analyzes feedback in a design. Takes a networkx digraph and returns the following:
+    
+    feedback_hierarchy - frozensets inside frozensets inside frozensets. Feedback hierarchy from large loops down to small loops
+    distances - a dictionary. Keys are frozensets of hinstances in the feedback loop. Item is the distance.
+    working_graph - networkx digraph. The resulting graph after all feedback has been folded down
