-Takes a stream and presents a stream that is a slice of the original stream.
-This is used when uploading media in chunks. In later versions of Python a
-stream can be passed to httplib in place of the string of data to send. The
-problem is that httplib just blindly reads to the end of the stream. This
-wrapper presents a virtual stream that only reads to the end of the chunk.
