* Firt commit. * First non-functional but correct implementation of BasicAuthority. Still needs: - Sealing infrastructure. * Punch a hole to give miner access to key store. * Fix test built. * Basic version of synchronous mining. This will seal a block whenever a new transaction comes through. To be made better we need a timer which will wait for one second after the last block before sealing a new one - better still would be to cooperatively interleave blocks with other sealing nodes. * Add tests. * Fix minor issues from repotting. * Address grumbles.
