-/* Hash table implementation.
- *
- * This file implements in memory hash tables with insert/del/replace/find/
- * get-random-element operations. Hash tables will auto resize if needed
- * tables of power of two in size are used, collisions are handled by
- * chaining. See the source code for more information... :)
