Cache Iterators - Iterators for navigating the cache structure
The DepIterator can iterate over two lists, a list of 'version depends'
or a list of 'package reverse depends'. The type is determined by the
structure passed to the constructor, which should be the structure
- that has the depends pointer as a member.
+ that has the depends pointer as a member. The provide iterator has the
+ same system.
