Everything except actually *using* BlockchainBDB is wired up, but the db itself is not yet working. Some error about user mem not large enough. I think I know what this error means, but I can't determine the cause. Notes: BerkeleyDB does not allow 0-indexing in its recno type databases, so block numbers *in the database* will be 1-indexed. Modifications to indexing have been made as needed.
