Register a real Custom Element using Vue.js.

- Only works with Vue ^0.11.0

- The browser must support the Custom Element API (currently Chrome only), or you need to include Polymer's [platform.js polyfill](https://www.polymer-project.org/docs/start/platform.html).

Available through npm, Component, Duo or Bower.

If you are using Vue globally, just include `vue-element.js` and it will automatically install the `Vue.element` method.

``` js

Vue.use(require('vue-element')) // installed

Vue.element({ /* ... */ })

Usage is the same as `Vue.component` - you pass in exactly the same options as if you are defining a Vue component. Two things to note:

- You don't need to manually instantiate a root level Vue instance. Custom Elements get auto-promoted when `document.registerElement` is called. You can also freely define the element before or after the markup.

- You can expose attributes with Vue's `paramAttributes` option. See the example folder to see it in action.
