Aggregates a Node.js stream and calls a callback with the accumulated result of first encountered error.

var aggregate = require('stream-aggregate')

aggregate(stream, function(err, result) {

Binary streams (which emit buffer objects) are aggregated into a single buffer, object streams -- into an array of emitted objects and streams of strings -- into a single concatenated string.

The main difference between this library and concat-stream is that stream-aggregate calls callback with an error which is usually desired behaviour.
