A simple package to do messaging tasks for publishing to the tangle (eg. MAM)

            // When deleting a stream, you close this stream, so you are not able to send new messages to this stream or receiving any messages.
            // Note: Because the previously messages are sent to the tangle, a permanode of iota could keep the old messages and your receivers could fetch messages that are published before the deletion.
            // To delete a stream, you can simply call `stream.deleteStream ()` which will send a deletion message to you stream which will tell you audience, that this stream has been closed and no new messages will be published anymore.
