How to use the mongodb-core.ReplSet function in mongodb-core

// Socket options
  var socketOptions = options.socketOptions && Object.keys(options.socketOptions).length > 0
    ? options.socketOptions : options;

  // Translate all the options to the mongodb-core ones
  clonedOptions = translateOptions(clonedOptions, socketOptions);
  if(typeof clonedOptions.keepAlive == 'number') {
    clonedOptions.keepAliveInitialDelay = clonedOptions.keepAlive;
    clonedOptions.keepAlive = clonedOptions.keepAlive > 0;
  }

  // console.log("=============== create CReplSet")
  // console.dir(clonedOptions)
  // Create the ReplSet
  var replset = new CReplSet(seedlist, clonedOptions);
  // Server capabilities
