Docs For Class AKUnarchiverZIP

Description

ZIP archive extraction class

Since the file data portion of ZIP and JPA are similarly structured (it's empty for dirs, linked node name for symlinks, dumped binary data for no compressions and dumped gzipped binary data for gzip compression) we just have to subclass AKUnarchiverJPA and change the header reading bits. Reusable code ;)
