Added test case for RayBounce example from Zach.

Zach wanted to get this test added to Automation.
This test is about Ray Bounce and Sun Path Direction.

This will **NOT need** merge to **master** because RVT file was created in Revit 2015 which cannot be open in Revit 2014. IF this test needs to be added in Master as well then we may need to ask @kronz  to create file in Revit 2014. Test case is going to be same.
