title: FitNesse/Slim String Operators
body: <p>Is it possible to express this in a Query Table in FitNesse with SLIM for .net:</p>
  
  <pre><code>contains(data)
  startswith(data)
  endswith(data)
  </code></pre>
  
  <p>I know from a <a href="https://stackoverflow.com/questions/767345/fitnesse-rowfixture-contains-startswith-endswith">previous question</a> it was possible for FitNesse/Fit with <code>cell handler loader</code>. I'm looking for the equivalent in Slim.</p>
