Type Hierarchy

##Hierarchy

The following type-hierarchy is propose, where italics indicate and abstract type.

• iterable
  • countable
    • ordered
      • queue
        • deque
          • list
            • linked_list
            • array_list
          • linked_deque
        • linked_queue
      • stack
      • data_set
        • dynamic_set
          • tree_set
            • tree_multiset
          • hash_set
            • hash_multiset
        • abstract_map
          • map
            • tree_map
            • hash_map
          • multimap
            • tree_multimap
            • hash_multimap
        • static_set

Once this initial set of data structures has been implemented, thought might be put into implementing graph and tree types.
