Now that the library logic and bisection are nearing completion in #96 and the relevant follow up issues (#110, #111), we should implement the daemon that puts it all together.

This requires:

• initial config with subjective initialization and list of peers
• simple address book to track peers and manage primary/backups
• detection module to make requests from backup peers, search for conflicts, and publish any verified ones
• concrete implementation of the store
• command line tool

To start, let's get a simple command line tool that works in the single peer case with a simple store, and then work on the detection module for detecting conflicts from backup peers.
