		## each()

		iterates through a series of middlewares (in parallel) for each item in an array

		```js
		var mw = require('dat-middleware');
		var app = require('express')();

		// a body of { arr: [1,2,3] }
		app.use(mw.body('arr').each(
		function (eachReq, res, next) {

		// if five arguments are accepted the current item and the origin req are passed
