Class Public methods
Creates a GzipReader or GzipWriter associated with io,
passing in any necessary extra options, and executes the block with the
newly created object just like File.open.
The GzipFile object will be closed
automatically after executing the block. If you want to keep the associated
IO object open, you may call #finish method in the block.
