This ticket is for adding a new fragment to the navigation drawer that holds a [TabLayout](https://developer.android.com/reference/android/support/design/widget/TabLayout.html). Each tab should be able to hold a child fragment. Swiping left/right in the child fragment should switch the tab. Clicking on the tab should switch to the respective fragment. Creating the child fragments with content is **not** part of this ticket.   Update: just added a mockup with a tab indicator
