+abstractions, each with multiple implementations.  The main abstractions
+provided by Edison are: Sequences such as stacks, queues, and dequeues;
+Collections such as sets, bags and heaps; and Associative Collections such as
+finite maps and priority queues where the priority and element are distinct.")
