title: coldfusion ignore undefined variables
body: <p>if I use </p>
  
  <pre><code>&lt;cfoutput&gt;#somevariable#&lt;/cfoutput&gt;
  </code></pre>
  
  <p>and <code>somevariable</code> is not defined I get an error, how can I prevent the error from occourring?
  is there a simple way of implementing a conditional that doesn't require a bunch of extra lines?</p>
