Transplanted a basic test setup from a new rails scaffold, and changed Rakefile to execute in scope of the app, to suppress some deprecation warning every time I ran a rake test. This last change also may have made it possible to have my (tautological) test run. Good start
Making corrections based on tests: Removed old obsolete code for getting paperclip image width and height
Had to remove a test or two, but now all tests are passing (heh). Ready to put up in travis.
