 * invoke a static creation method followed by an instance mutator (if needed):
 * <p/>
 * <code>
 * import static org.jclouds.joyent.cloudapi.v6_5.compute.options.JoyentCloudTemplateOptions.Builder.*;
 * <p/>
 * ComputeService client = // get connection
 * templateBuilder.options(inboundPorts(22, 80, 8080, 443));
 * Set<? extends NodeMetadata> set = client.createNodesInGroup(tag, 2, templateBuilder.build());
