Create streams that cannot be closed with the normal close() mechanism. Instead, a reallyClose() method is provided while the close() method does nothing.

This is useful when you have a stream to pass to methods that either read or write using the stream. If any of the methods call the stream's close method before you are done with the stream, this class is useful. Simply wrap your stream in one of the NoClose Streams, and pass that around. When the other method calls the close method it will have no effect. You can later close your stream by calling the reallyClose() method.
