Ref Issue #6: moved files to test directory, tests do not pass

[tiekneeshrimp]

          @tiekneeshrimp will move directories:

• [x] move source code in concerto to src/concerto
• [x] Move test code to the tests directory and confirm the tests still pass
• [ ] Modify the test code if they don't pass
