AsyncArray
==========
Yet another control flow library after getting fustrated with previous ones.
## Usage
The `next` callback takes the arguments (error, data)
 var AsyncArray = require('async-array')
 var array = new AsyncArray([1, 2, 3, 4])
 array
 .map(function (item, i, next) {
 db.query('SELECT * FROM x WHERE id = ?', [item], next)
 })
 .done(function (error, results) {
 console.log("Got me database listings partner!")
 })
 .forEach(function (db_result, i, next) {
 doSomethingAsync(db_result, next)
 })
 .exec()
As you can see, you can chain stuff and the result is passed along from the previous operation. If you don't call `exec` immediately you can store the operation to be executed at some later time.
`AsyncArray` inherits from `Array` with the following methods added:
- map
- mapSerial
- filter
- filterSerial
- forEach
- forEachSerial
Serial methods do things one after another instead of in parallel.
