title: Creating a slide in side view controller
body: <p>I would like to know how to create a 'side' View Controller. They are becoming increasingly popular...</p>
  
  <p>Apps such as Facebook and Words with Friends use these on IOS, these are two extremely popular apps so will not upload a picture for this.</p>
  
  <p>When clicking on the = icon in the top navigation a side navigation/menu theme view controller is shown on the side, whilst the navigation controller current view controller is moved slightly to the other side. For example, you can still see the original view controller slightly on the right side, whilst a list of available options are shown.</p>
  
  <p>Does anyone know how this would be achieved or a tutorial of how to accomplish this?</p>
