This class can be used to compress any data written to QIODevice or
decompress it back. Compressing data sent over a QTcpSocket is a good
example.

/**
Unfortunately, as QIODevice doesn't support flush() by itself, the
only thing this method does is write the compressed data into the
device using Z_SYNC_FLUSH mode. If you need the compressed data to
actually be flushed from the buffer of the underlying QIODevice, you
need to call its flush() method as well, providing it supports it
(like QTcpSocket does). Example:
\code
QuaZIODevice dev(&sock);
dev.open(QIODevice::Write);
dev.write(yourDataGoesHere);
dev.flush();
sock->flush(); // this actually sends data to network
\endcode
This may change in the future versions of QuaZIP by implementing an
ugly hack: trying to cast the QIODevice using qobject_cast to known
flush()-supporting subclasses, and calling flush if the resulting
pointer is not zero.
