title: Log to output window when using T4
body: <p>I'm using T4 for code generation. Its working well but one thing I'd like to do is some simple logging, I'm happy if this simply took the form of throwing messages into the Output window.</p>
  
  <p>Does anyone know a way of doing this?</p>
  
  <p>Alternatively, I know there exists Error() &amp; Warning() methods for dumping stuff into the Error List pane, is there anything similar for dumping informational messages?</p>
