title: Calling a yeoman generator after a generator has finished
body: <p>I am looking to call another yeoman generator once the first generator has finished installing, this will be based on an answer I give for one of the prompts.</p>
  
  <p>I have tried calling it at the end.</p>
  
  <pre><code>end: function () {
    this.installDependencies({
      callback: function () {
  
        if( this.generator2 ){
          shell.exec('yo generator2');
        }
  
      }.bind(this)
    });
  },
  </code></pre>
  
  <p>This runs generator2, but I am unable to answer any prompts.</p>
  
  <p>These are 2 separate generators, so I cannot make the second a sub generator.</p>
