Worked on UI for the course news feature. Added another navigation controller with a master-detail view. Master view is a table view that should show the titles for news items. Two segues are performed from this view, one to the detail view that shows the contents of the news item by clicking on the table cell of the item. If the button in the upper right corner of the news master view is pressed, it is taken to a view that will be used to add new rss sources to the app.
