title: react-native-router-flux tabbar not showing
body: <p>I'm having a trouble showing the tabbar in react-native-router-flux.</p>
  
  <p>Im creating my scenes like this. I was able to show the first tab of the tabbar but can't make the tabbar to show at the bottom. Thanks for any help. </p>
  
  <pre><code>const scenes = Actions.create(
    &lt;Scene key='root' tabs={true} unmountScenes
        component={connect(stateToProps)(Switch)}
        selector={props =&gt; props.isLoggedIn ? 'tabBar' : 'login'}&gt;
      &lt;Scene key='splash' component={Splash} title=''
        hideNavBar={false} /&gt;
      &lt;Scene key='login' component={Login} title=''
        hideNavBar={true} /&gt;
      &lt;Scene key='signup' component={Signup} title='Signup'
        hideNavBar={false} /&gt;
      &lt;Scene key="tabBar" tabs icon={TabbarIcon} tabBarStyle={styles.tabBarStyle}&gt;
        &lt;Scene key='home' component={Home} title='Home' initial={true}
          icon={TabbarIcon} /&gt;
        &lt;Scene key='diary' component={Diary} title='Diary'
          icon={TabbarIcon} /&gt;
        &lt;Scene key='cabinet' component={Cabinet} title='Cabinet'
          icon={TabbarIcon} /&gt;
      &lt;/Scene&gt;
    &lt;/Scene&gt;
  );
  </code></pre>
