Bully

node.js module to elect a master peer in a distributed system. This module uses the
Bully Algorithm for the election
process. Unresponsive/offline peers will be recognized through heartbeat timeouts.

`bash
npm install bully
`

`javascript
var Bully = require('bully');

var opts = { id: "id", / unique identifier of this peer /
peers: [], / event emitter instances of other peers /
me: me / event emitter instance of local peer /
}

var bully = new Bully(opts);

bully.on("master", function () {
console.dir('I am now the master');
});
bully.on("stepped_down", function () {
console.dir('Unfortunately I had to step down from my responsibilities');
});

`

$3

`javascript
var EventEmitter = require('events').EventEmitter;

var peer = new EventEmitter();
peer.id = 'anoter_unique_id';

bully.addPeer(peer);
`

$3

`javascript
bully.removePeer("peers_unique_id");
`

$3

`javascript
bully.on("error", function (err) {
// handle error here
