Rafa.js is a Javascript framework for building concurrent applications.

Merge two stream nodes and handle messages from each; fan-in. A single done message
will be sent once all streams have sent a done message.

```js
// merge(...Stream): Stream
var stream1 = Rafa.stream();
var stream2 = Rafa.stream();
var values = [];
var dones = [];

stream1.merge(stream2).each(v => values.push(v)).done(v => dones.push(v));

stream1.write(1);
stream2.write(2);
stream1.write(3, true);
stream2.write(4, true);

// values: [1,2,3,4]
// dones: [4]  ! BUG
```
