I still had some stuff of Nathan Kelly's (FileTransfer-WebSocketPair) sitting on my USB. Had already commited the Themes folder at the time, 2 years back. Not sure if he wanted this additional folder commited. But I didn't want to delete it and decided it will be better off on SVN. When we use his project, if we find we didn't need this test folder, we can remove it from svn then.
