Peter/slide directions3

- Adds UI changes to multi result, single result, route preview fragment, and routing fragments. 
- Adds the ability to slide bottom of the routing fragment to reveal directions in the view raised up. 
By simulating the clicks with setCurrentItem() we are kind of just testing ViewPager here.

Would be better to use Robolectric.clickOn(), View.performClick(), or even manually invoke the callbacks so we are actually testing our code.
