Changelog: Setup & Foundation - bcoin - express - mongo - eslint - logging Status: Bcoin syncs over network, uses a local leveldb to store blocks and checkpoints. Block event saves data to mongo. Express endpoint for block hashes, stubbed to reply with blockhashes until mongo models are finalized. ToDo: Move config out of code
