   Cache Iterators - Iterators for navigating the cache structure
   
   The iterators all provides ++,==,!=,->,* and end for their type.
   The end function can be used to tell if the list has been fully
   traversed.
   
   Unlike STL iterators these contain helper functions to access the data
   that is being iterated over. This is because the data structures can't
   be formed in a manner that is intuitive to use and also mmapable.
   
   For each variable in the target structure that would need a translation
   to be accessed correctly a translating function of the same name is
   present in the iterator. If applicable the translating function will
   return an iterator.

   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. The provide iterator has the
   same system.
