title: Converting Regular Backbone App to use Marionette.js
body: <p>I am considering changing our current application to use Marionette.  The trouble is that there is currently a whole number of different views, models, and collections that have been made by other developers that use regular Backbone.</p>
  
  <p>I figure I can't really convert the whole application in one go especially considering I didn't develop a whole bunch of it. I am considering just starting with the Application object and Router.  </p>
  
  <p>Is this going to be possible?  Can I start with that and convert the actual views later?</p>
