Using ZipArchive

In this repository, there is an XCode project "ZipArchive". Here's the basic instructions for using it in your iOS app:

1. Get the ZipArchive source.
2. Build ZipArchive.
3. Open your iOS project
4. Add items like so:

You can add the output "ZipArchive.a" file directly, but if you add it via the XCode Project, then XCode will understand the dependency on the ZipArchive project and rebuild it if necessary.

You will need these three files in your project:

1. ZipArchive.h -> so your app knows about ZipArchive
2. ZipArchive.a -> the actual code compiled.
3. libz -> the system Z compression library which does the actual data compression/decompression

Refer to the ZipArchive.m and ZipArchive.h files for more documentation.

(I'm trying to figure out if doxygen can output in a way that github can use... but haven't found anything yet.)
