trend/cardinality tracking server

##HTTP Usage: // increment a key // g (group name) // k (key name) // v (optional; increment amount, defaults to 1) http://localhost?g=users&k=jason&v=1 http://localhost?g=plays&k=catvideo&v=1

// get the top n results for a group
// g (group name)
// n (count to return; capped at 200)
http://localhost/top?g=users&n=100

// Sample output:
{
	"running": true,
	"timestamp": "2014-07-20 14:56:07.950249659 -0700 PDT",
	"render_time": "32.07us",
	"decay_rate": 0.05,
	"decay_floor": 1,
	"result_set": {
		"users": {
			"table_size": 1,
			"cardinality": {
				"percent": 0.2,
				"duration": "1m0s",
				"uniques": 1,
				"total": 5
			},
			"result_count": 1,
			"results": [
				{
					"name": "jason",
					"score": 4.494319519969077
				}
			]
		}
	}
}

##Websocket Usage: websockets are available for consuming reports regularly

// console test:

// open a connection
var sock = new WebSocket("ws://localhost/sub");

// simple bind for reporting on all events
sock.onclose = sock.onerror = sock.onmessage = sock.onopen = console.log.bind(console);

// subscribe to log(s)
sock.send(JSON.stringify(["users","plays"]))

// clear all subscriptions
sock.send("[]")
