-> Implement C++0x features (rvalue references)
-> Offer bidirectional iterator for hashtables
-> Non-array buckets
-> Document incremental<> option better
-> Assure stable order for optimize_multikey and inverse order otherwise
-> add an option to unordered containers to get O(1) traversal and begin()/end() even with very low load factors
