A mechanism for reading zip-compressed data from a stream

A ZipInputStream is a mechanism for reading data from a stream, where the data is in a zip-compressed format. A stream is usually comprised of data being read from a local file, or data being transmitted from a remote server over a network protocol such as HTTP or FTP. As the data is read from the stream, the ZipInputStream decompresses it, and returns the uncompressed data to the application.
