## Combine (stream1,...,streamN)

Turn a pipeline into a single stream. `Combine` returns a stream that writes to the first stream

and reads from the last stream. 

Listening for 'error' will recieve errors from all streams inside the pipe.

```js

var Combine = require('stream-combiner')

var es      = require('event-stream')

Combine(                                  // connect streams together with `pipe`

  process.openStdin(),                    // open stdin

  es.split(),                             // split stream to break on newlines

  es.map(function (data, callback) {      // turn this async function into a stream

    var repr = util.inspect(JSON.parse(data))  // render it nicely

    callback(null, repr)

  }),

  process.stdout                          // pipe it to stdout !

)

```

Can also be called with an array:

```js

var combinedStream = Combine([

  stream1,

  stream2,

]);

```

Or to combine gulp plugins:

```js

function coffeePipe() {

  return Combine(

    coffeescript(),

    coffeelint.reporter('fail').on('error', function(){

      gutil.beep()

      gulp.run('lint')

    })

}

//usage:

gulp.src().pipe(coffeePipe());

```
