title: Make UICollectionViewController paged sections
body: <p>I'm making a collectionView where 1 section means 1 calendarday, I want to make it paged so it only shows 1 section (1 day) at a time so i can swipe (scroll) to the left or right to show me the next day. </p>
  
  <p>I cant seem to find a solution or im dont know the right keywords...</p>
  
  <p>im mainly using the storyboard and my collectionViewController is embedded in a ContainerView in a normal UIViewController.</p>
  
  <p>Any help is much appreciated!</p>
