Sugar way to manage your pendings.

## Example

```javascript

var Ready = require('..')

function Concat() {

  this.ready = Ready()

}

Concat.prototype.add = function(file) {

  this['addType' + (rand() % 2 + 1)](file)

}

Concat.prototype.addType1 = function(file) {

  var self = this

  this.ready.delay(

    new Promise(function (resolve) {

      setTimeout(function() {

        self.push('{' + file.slice(-1) + '}')

        resolve()

      }, rand())

    })

  )

}

Concat.prototype.addType2 = function(file) {

  var cb = this.ready.delay()

  var self = this

  setTimeout(function() {

    self.push('[' + file.slice(-1) + ']')

    cb()

  }, rand())

}

Concat.prototype.push = function(source) {

  console.log(source.toUpperCase())

}

Concat.prototype.end = function() {

  var self = this

  this.ready.then(function () {

    self.push('\n# end #')

  })

}

function rand() {

  return Math.ceil(Math.random() * 100)

}

var concat = new Concat()

concat.add('./a')

concat.add('./b')

concat.add('./c')

concat.end()

// [B]

// {C}

// [A]

// 

// # END #

```

## class Ready()

Instances are `thenable` objects.

### .then(onFulfilled, onRejected)

### .catch(onRejected)

### .delay(n)

If `n` is `Number`, it specifies the amount of time to be delayed.

If `n` is `Promise`, it delays until the promise resolves or rejects.

Otherwise, it delays until the returned callback is called.
