Concatenate a readable stream's data into a single array.

## API

```js
var toArray = require('stream-to-array')
```

### toArray([stream], [callback(err, arr)])

Returns all the data objects in an array.
This is useful for streams in object mode if you want to just use an array.

```js
var stream = new Stream.Readable()
toArray(stream, function (err, arr) {
  assert.ok(Array.isArray(arr))
})
```

If `stream` is not defined, it is assumed that `this` is a stream.

```js
var stream = new Stream.Readable()
stream.toArray = toArray
stream.toArray(function (err, arr) {

})
```

If `callback` is not defined, then it returns a promise.

```js
toArray(stream)
  .then(function (parts) {

  })
```

If you want to return a buffer, just use `Buffer.concat(arr)`

```js
toArray(stream)
  .then(function (parts) {
    var buffers = []
    for (var i = 0, l = parts.length; i < l ; ++i) {
      var part = parts[i]
      buffers.push((part instanceof Buffer) ? part : new Buffer(part))
    }
    return Buffer.concat(buffers)
  })
```
