/**
 * Contains options supported by the
 * {@link ComputeService#createNodesInGroup(String, int, TemplateOptions)} and
 * {@link ComputeService#createNodesInGroup(String, int, TemplateOptions)}
 * operations on the gogrid provider.
 * 
 * Usage The recommended way to instantiate a
 * {@link GoGridTemplateOptions} object is to statically import
 * {@code GoGridTemplateOptions.*} and invoke a static creation method followed
 * by an instance mutator (if needed):
 * 
 * 
 * 
 * import static org.jclouds.compute.options.GoGridTemplateOptions.Builder.*;
 * ComputeService client = // get connection
 * templateBuilder.options(inboundPorts(22, 80, 8080, 443));
 * Set<? extends NodeMetadata> set = client.createNodesInGroup(tag, 2, templateBuilder.build());
 * 
 * 
 * TODO add GoGrid specific options
