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)
})
```
