	//  ``1 => first string``
	//  ``2 => second string``
	//  ``3 => third string``
	while (iter.next (out key, out val)) {
		print ("%d => %s\n", key, val);

Creation methods:

• public HashTableIter (HashTable<K,V> table)
  Initializes a key/value pair iterator and associates it with hash_table.

Methods:

• public unowned HashTable<K,V> get_hash_table ()
  Returns the GenericSet associated with this.
• public bool next (out unowned K key, out unowned V value)
  Advances this and retrieves the key and/or value that are now pointed to as a result of this advancement.
• public void remove ()
• public void steal ()
  Removes the key/value pair currently pointed to by the iterator from its associated GenericSet, without calling the key and value destroy functions.
