title: Does FalcorJS router support returning promises?
body: <p>In the examples (as far as I can tell, maybe I missed some subtlety in the router examples), raw values are returned from the get function. Is there  a way to return a callback or promise in the get function? What's the best way to do that?</p>
  
  <p>For now, I'm guessing I use Q.defer?</p>
