Perl module for accessing a hashes internal iterator

 Hash::StoredIterator gives access to get, set, and init the iterator inside
 a hash. This allows one to store the current iterator, use
 each/keys/values/etc, and then restore the iterator, this helps to ensure
 that nobody interacts badly with other users of the iterator.
 .
 In perl all hashes have an internal iterator. This iterator is used by the
 each() function, as well as by keys() and values(). Because these all share
 use of the same iterator, they tend to interact badly with eachother when
 nested.
