OK, so we should be able to iterate keys.  And the keys are not stored in  
the trie structure itself.  So how does one iterate the keys of the  
container without reconstructing them from the trie nodes using the heap?   
Forget about interfaces, pretend you were writing it separate from  
dcollections.
