Isolate processes documentation

I am trying to isolate the processes of my tests as outlined in the advanced tutorial but I am having some issues. In particular, the example shows moving each process into its own scala class like so:

import io.gatling.core.Predef._
import io.gatling.core.scenario.Simulation
import io.gatling.http.Predef._
import scala.concurrent.duration._

class SearchSimulation extends Simulation {
object Search {

  val search = exec(http("Home") // let's give proper names, as they are displayed in the reports

First, I should say that I am fairly new to Scala so this is likely user error.  But, when I attempt to create an object like the one above I get an error that the value "exec" is not found.  It is the first line (val search = exec(http("Home")) that is being flagged.  I thought maybe there was some import I was missing but after review it does not seem to be the case, or it could be that I am doing the import incorrectly.  I also grabbed the source for gatling and reviewed the AdvancedSimulationStep05.scala and it has something very similar.  What am I missing?

Answering my own question. Upon closer examination I was following the template for gatlin 2.1.1 and was using 2.0. i have since created a new project using 2.1.1 and the code below now works.
