Describes a ZIP archive file containing multiple sub-files.

Typically the sub-files are ROOT files. Notice that the ROOT files should not be compressed when being added to the ZIP file, since ROOT files are normally already compressed. Such a ZIP file should be created like: zip -n root multi file1.root file2.root which creates a ZIP file multi.zip. A ZIP archive consists of files compressed with the popular ZLIB compression algorithm. The archive format is used among others by PKZip and Info-ZIP. The compression algorithm is also used by GZIP and the PNG graphics standard. The format of the archives is explained briefly below. This class provides an interface to read such archives. A ZIP archive contains a prefix, series of archive members (sub-files), and a central directory. In theory the archive could span multiple disks (or files) with the central directory of the whole archive on the last disk, but this class does not support such multi-part archives. The prefix is only used in self-extracting executable archive files. The members are stored in the archive sequentially, each with a local header followed by the (optionally) compressed data; the local header describes the member, including its file name and compressed and real sizes. The central directory includes the member details again, plus allows an extra member comment to be added. The last member in the central directory is an end marker that can contain a comment for the whole archive. Both the local header and the central directory can also carry extra member-specific data; the data in the local and global parts can be different. The fact that the archive has a global directory makes it efficient and allows for only the reading of the desired data, one does not have to scan through the whole file to find the desired sub-file. The Zip64 extensions are supported so files larger than 2GB can be stored in archives larger than 4 GB. Once the archive has been opened, the client can query the members and read their contents by asking the archive for an offset where the sub-file starts. The members can be accessed in any order.
