flatten

A tiny utility to flatten arrays of arrays (of arrays, etc., recursively, infinitely or to an optional depth) into a single array of non-arrays.

example:

```js

var flatten = require('flatten'); undefined flatten([1, [2, 3], [4, 5, 6], [7, [8, 9]], 10]) [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ] flatten([1, [2, [3, [4, [5]]]]], 2) [ 1, 2, 3, [ 4, [ 5 ] ] ] ```

install:

npm install flatten
