Morgue: modular PHP archive file reader and writer

This package aims to become a drop-in replacement for the ZipArchive class provided by the PHP zip extension.

The extensions ZipArchive class wraps the libzip C library. This provides a widely used, tested, fast and reliable way to read/modify ZIP files. The main limitation in using libzip is the inability of ZipArchive to work with PHP stream wrappers/filters, e.g. open a ZIP file directly from a HTTP URL.
