Add some tests based on the current behavior, doing interesting checks for different sets of branches, ranges, and the --boundary option. This sets a baseline for the behavior and we can extend it as new options are introduced. Store and output a 'batch_nr' value so we can demonstrate that the paths are grouped together in a batch and not following some other ordering. This allows us to test the depth-first behavior of the path-walk API. However, we purposefully do not test the order of the objects in the batch, so the output is compared to the expected output through a sort. It is important to mention that the behavior of the API will change soon as we start to handle UNINTERESTING objects differently, but these tests will demonstrate the change in behavior.
