 * IQ packet used by Smack to bind a resource and to obtain the jid assigned by the server.
 * There are two ways to bind a resource. One is simply sending an empty Bind packet where the
 * server will assign a new resource for this connection. The other option is to set a desired
 * resource but the server may return a modified version of the sent resource.<p>
