Added rspec/autotest with working spec (Ch 8.2)
Skeleton for RGR cycle, working files (Ch 8.3)
Updated movies_controller_spec (Ch 8.4)

2/3 tests pass, #3 fails because spec is still in works
Textbook references files we created, but I couldn't find
Need to edit controller to return mock values in correct format
-> Continue with textbook to create necessary models/views/ctl-methods
