Example
Queue with one consumer:

var queue = new Queue;
queue.push('a', 1);
queue.push('b', 2);
queue.push('c', 2);
console.log(yield queue.next());
console.log(yield queue.next());
console.log(yield queue.next());
})();

Queue with multiple consumers:
var co = require('co');
var Queue = require('co-priority-queue');
co(function *(){

queue.push('c', 2);
var consumers = [queue.next(), queue.next(), queue.next()];
console.log(yield consumers);
