Demo and API docs

##<iron-ajax>

The iron-ajax element exposes network request functionality.

<iron-ajax
    auto
    url="https://www.googleapis.com/youtube/v3/search"
    params='{"part":"snippet", "q":"polymer", "key": "YOUTUBE_API_KEY", "type": "video"}'
    handle-as="json"
    on-response="handleResponse"
    debounce-duration="300"></iron-ajax>

With auto set to true, the element performs a request whenever its url, params or body properties are changed. Automatically generated requests will be debounced in the case that multiple attributes are changed sequentially.

Note: The params attribute must be double quoted JSON.

You can trigger a request explicitly by calling generateRequest on the element.

##<iron-request>

iron-request can be used to perform XMLHttpRequests.

<iron-request id="xhr"></iron-request>
...
this.$.xhr.send({url: url, body: params});
