// yourself, and you must load it prior to dojox.rpc.Rest.
// summary:
// This provides a HTTP REST service with full range REST verbs include PUT,POST, and DELETE.
// description:
// A normal GET query is done by using the service directly:
// | var restService = dojox.rpc.Rest("Project");
// | restService("4");
// This will do a GET for the URL "/Project/4".
// | restService.put("4","new content");
// This will do a PUT to the URL "/Project/4" with the content of "new content".
// You can also use the SMD service to generate a REST service:
// | var services = dojox.rpc.Service({services: {myRestService: {transport: "REST",...
// | services.myRestService("parameters");
//
// The modifying methods can be called as sub-methods of the rest service method like:
// | services.myRestService.put("parameters","data to put in resource");
// | services.myRestService.post("parameters","data to post to the resource");
// | services.myRestService['delete']("parameters");
