v0.15.12
Another round of resolving tuning. Deeply nested objects were sometimes still getting muddled with stage two resolving (building a model). This update fixes that, and adds a test to build out the digital ocean tree as a model (which resolves thousands of deeply nested files).
Also a flatter report model was added for change detections. Instead of a tree of changes, a flat set of change slices is provided.
