* Move route loading logic to a common place.

* Add router events.

* Add EventEmitter's core API methods.

* Add example app for loading events and docs.

* Fix some typos.

* Get rid of Router.ready()

* Remove events package.
It's already shipping with webpack.

* Handling aborting properly.

* Expose simple attribute based events listener API.
Removed the proposed event listener API from the public API.

* Remove error logged when there's an abort error.
There are many other ways to capture this error.
So, it doesn't look nice to print this always.

* Change router events to pass only the current URL as arguments.

* Add a section about Cancelled Routes to README.
