DBM::Deep::Iterator - iterator for FIRSTKEY() and NEXTKEY()
This is an internal-use-only object for DBM::Deep. It is the iterator for FIRSTKEY() and NEXTKEY().
The constructor takes a hashref of params. The hashref is assumed to have the following elements:
o engine (of type DBM::Deep::Engine
o base_offset (the base_offset of the invoking DBM::Deep object)
This method takes no arguments.
It will reset the iterator so that it will start from the beginning again.
This method returns nothing.

DBM::Deep::Iterator::BucketList - mediate between DBM::Deep::Iterator and DBM::Deep::Engine::Sector::BucketList
This is an internal-use-only object for DBM::Deep. It acts as the mediator between the DBM::Deep::Iterator object and a
This object, despite the implied class hiearchy, does NOT inherit from DBM::Deep::Iterator. Instead, it delegates to it, essentially acting
as a facade over it. "get_next_key" in DBM::Deep::Iterator will instantiate one of these objects as needed to handle an BucketList sector.
The constructor takes a hashref of params and blesses it into the invoking class. The hashref is assumed to have the following elements:
o iterator (of type DBM::Deep::Iterator
o sector (of type DBM::Deep::Engine::Sector::BucketList
This takes no arguments.
This returns true/false indicating whether this sector has any more elements that can be iterated over.
This takes no arguments.
This returns the next key pointed to by this bucketlist. This value is suitable for returning by FIRSTKEY or NEXTKEY().
If the bucketlist is exhausted, it returns nothing.
