Promise queue for Node.js
npm install promiseqPromiseQ 
========
Promise queue for node.js
This package will maintain a queue of promises and use promises to return
completion of a task as well as completion of the queue.
Useful for migrations and work queues. This is inspired by promise-queue but
built for Node.js and uses bluebird to provide the promises and async.queue
to facilitate the queue operations.
``jsQ
var P = require('bluebird') //or whatever promise library you prefer such as
var PromiseQueue = require('promiseq')
var workerCount = 4 //defaults to number of cpus when left null
//setup the queue
var queue = new PromiseQueue(workerCount)
//make a job
var job = function(){
return new P(function(resolve){
process.nextTick(resolve)
})
}
//add a single job
queue.push(job).then(function(){console.log('Job complete')})
//close the queue and listen for the drain
queue.close().then(function(){console.log('Queue closed and drained')})
`
stat in favor of complete
* Added stat that tracks error counts
* Added succeeded stat which is (complete - failed)$3
* Update dependencies
* Add canAccept() function to queue to see if slots are available
* Add allowance to allow overloading of canAccept()` function
