continuum - P2P replicated document storage service

*	put swarm ID into the document	tv	12 hours	4	-6/+27
\|
*	add genesis flag and never give up	tv	12 hours	3	-76/+112
\| \| \| \| \| \| \| \| \|	The --genesis flag has been introduced to start with a new document. This prevents restarts to accidentally start with a new document and accept reads/writes, causing a second swarm to appear. Additionally, bootstrapping doesn't timeout anymore as that's of no use for nobody.
*	compact remake fixes base at the commit	tv	26 hours	5	-40/+138
\| \| \| \| \| \| \|	Instead of fixing base heads at when proposed, compact fixes them when committing. This shrinks the window where writes can be lost if their author restarts to the switch delay; during replace and import remakes writes can still be lost during the voting period.
*	fix wording around swarm key admission	tv	26 hours	2	-3/+3
\|
*	allow superseding expired remakes	tv	27 hours	4	-26/+279

\|
*	bound stable-hub degree	tv	28 hours	1	-4/+46
\| \| \| \| \| \|	Each stable member can be preferred at most by 4*k members. The budget is spent in key order, which is the same on every node, so the graph stays deterministic, symmetric and connected.
*	coalesce announcements	tv	28 hours	3	-2/+60
\|
*	cache heads	tv	28 hours	7	-24/+61
\| \| \| \|	To reduce the number of write locks, heads are now cached.
*	corroberate newer epochs	tv	28 hours	1	-11/+53
\|
*	follow and download from ready members only	tv	28 hours	3	-3/+29
\|
*	being caught up needs some heads	tv	29 hours	1	-5/+9
\| \| \| \| \| \| \| \| \| \| \|	A sync message from a ready peer only completes the initial sync if that peer has at least one head. A peer with an empty document can no longer make a joiner ready on an empty store: a misconfigured second swarm, or a genesis node in its first seconds. Effect on a brand-new swarm: a joiner now waits until the genesis node has registered itself in the member list, which happens within about 5 s of it becoming ready.

\|
*	wire up --mycelium-tcp-listen-port	tv	34 hours	1	-2/+5
\| \| \| \| \|	It wasn't used before, causing the supervised daemon to always pick a random one.
*	introduce majority voting on remakes	tv	35 hours	7	-95/+406
\|
*	add electorate	tv	36 hours	3	-8/+109
\| \| \| \| \|	For an upcoming change in remake coordination, nodes now maintain their self-assessed liveness in the document.

\| \| \| \|	GET /admin/stats to retrieve all stats.
*	add swarm stats	tv	42 hours	9	-1/+238
\|
*	add traffic counter	tv	43 hours	9	-12/+270
\| \| \| \| \| \| \| \| \| \|	This introduces a new wrapper that counts messages and payload bytes per peer, split by kind (hello, helloReply, sync, ping, pong), each sent, received and refused. The traffic counter goes around the firewall, which means messages dropped outbound are still counted as sent, and messages dropped inbound don't count as received.
*	nodes prefer stable neighbours	tv	43 hours	1	-10/+89
\|
*	assess swarm stability	tv	43 hours	8	-11/+330

\|
*	record RTT from keepalive messages	tv	44 hours	7	-20/+148
\|
*	pull missing changes	tv	44 hours	7	-5/+162
\| \| \| \| \| \|	Nodes push changes to their neighbours but don't relay them directly. In a partial mesh, nodes can learn about missing changes via keepalive messages and can pull them from their neighbours.
*	find reachable neighbours	tv	44 hours	3	-55/+162
\|
*	sync with neighbours	tv	44 hours	6	-4/+171
\|
*	add neighbour graph	tv	45 hours	2	-0/+180
\|
*	add member registry	tv	45 hours	4	-1/+73
\|
*	use nonce in handshake	tv	45 hours	5	-2/+39
\| \| \| \| \|	To prevent stale hello replies to cause joins and thus stale sessions, each run gets a random ID, which used as nonce in the handshake.
*	drain queued messages on startup	tv	45 hours	1	-2/+48
\|
*	consolidate backoff code	tv	46 hours	4	-49/+99
\|
*	retry using fresh messages	tv	46 hours	3	-170/+180
\| \| \| \| \|	Don't store encoded messages but retry using a newly generated one. That way any accumulated changes can be delivered at once.
