Add Files to a ZIP Using AddFile

This example demonstrates how to use the AddFile method to add files from the local filesystem to a ZIP archive.

The example adds two files:

One file with its relative directory path preserved
One file stored using only its filename

The AddFile method adds references to local filesystem files. The files are not actually read or compressed until a Write* method is called.
