improve efficiency of multilayered indirect blocks clean up tests panic cleanup clean up logic, improve readability add final root node to the dagservice upon creation importer: simplified dag generation test: updated hashes using latest code @whyrusleeping this is why the sharness tests were failing: the hashes are added manually to make sure our generation doesn't change. cleanup after CR fix merkledag tests fix small block generation (no subblocks!)
