Package Cache Generator - Generator for the cache structure.
This builds the cache structure from the abstract package list parser.
+ Each archive source has it's own list parser that is instantiated by
+ the caller to provide data for the generator.
+
+ Parts of the cache are created by this generator class while other
+ parts are created by the list parser. The list parser is responsible
+ for creating version, depends and provides structures, and some of
+ their contents
