title: QueryOver IN Clause?
body: <p>I want to simulate this query:</p>
  
  <pre><code>SELECT * FROM FOO WHERE ID IN (1,2,3)
  </code></pre>
  
  <p>How can I do this in FNH?</p>
  
  <pre><code>var ids = new List&lt;int&gt;{1,2,3};
  var results = session.QueryOver&lt;Foo&gt;().Where( x=&gt; ids.Contains(x.id) );
  </code></pre>
  
  <p>But that does not work, just gives me an "unrecognized method call" exception.</p>
  
  <p>Any ideas?  This must be a common request.</p>
