rafa/docs/Stream-enumerate.md

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

Subscribe to an enumerator and emit its values through the stream. This is a
concurrent iteration: the stream will not ask for the enumerator's next value
until it is done processing the previous value. And the enumerator will not 
provide a new value to the stream until it has one.

```js
// enumerate(Enumerator): Stream
var stream = Rafa.stream();
var results = { vals: [] };

stream.
  .each(v => results.vals.push(v))
  .done(v => results.last = v);

stream.enumerate(Rafa.Enumerator.array([1,2,3,4]);

// results:
//   - vals: [1, 2, 3, 4]
//   - last: 4
```
