Library for using DOM elements as well as Ajax requests

### `Rx.Scheduler.microtask`
[Ⓢ](https://github.com/Reactive-Extensions/RxJS-DOM/blob/master/src/microtask.js "View in source")

Gets an `Rx.Scheduler` that schedules work on the `window.MutationObserver` for immediate actions.  If this is not available, this defaults to `window.setImmediate`, `window.postMessage`, `window.MessageChannel`, `script.onreadystatechanged` and finally `setTimeout` in that order based upon what your browser supports.

#### Example
```js
var obs = Rx.Observable.return(
  42,
  Rx.Scheduler.mutationObserver);

obs.subscribe(function (x) {
  // Scheduled using a MutationObserver
  console.log(x);
});

// => 42
```
