`app-auth`
Simple polymer custom element for authentication module in your application

@demo demo/index.html

### Event Throw
`app-auth` will throw these custom events so host element can listen to them:

Event Name | Description | Thrown Attribute(s)
`init-error` | Error event because login and logout URL not set | -
`login` | `app-auth` currently logging in given username | username:String
`logout` | `app-auth` currently logging out given username | username:String
-->
