title: Adding event to the calendar with apple watch
body: <p>One of our requirements is to allow the user to add a specific date/time that is recurring/nonrecurring to the calendar by using the watch. </p>
  
  <p>What is best practice for doing this? </p>
  
  <p>Should I send the parameters to the parent with <code>WKInterfaceController.openParentApplication</code> and have the phone add the event?</p>
  
  <p>Or is it preferable to have the actual watch add the event to the calendar? Which means importing the <code>EKEventStore</code> in the watchkit extension</p>
