title: Setting up a TTSectionedDataSource
body: <p>I am trying to create a TTTable with multiple sections. I have everything laid out inside of an array that looks a little something like this.</p>
  
  <pre><code>                       @"Styles",
                         [TTTableTextItem itemWithText:@"Styled Views" URL:@"tt://styleTest"],
                         [TTTableTextItem itemWithText:@"Styled Labels" URL:@"tt://styledTextTest"],
  
                         @"Controls",
                         [TTTableTextItem itemWithText:@"Buttons" URL:@"tt://buttonTest"],
                         [TTTableTextItem itemWithText:@"Tabs" URL:@"tt://tabBarTest"],
                         [TTTableTextItem itemWithText:@"Composers" URL:@"tt://composerTest"],
  </code></pre>
  
  <p>How do I put these values inside of my data source. I've tried:</p>
  
  <pre><code>self.dataSource = [TTSectionedDataSource dataSourceWithArrays:myArray]; 
  </code></pre>
  
  <p>However that seems to make my application crash. </p>
