I guess there is a mistake in polymer documentation

[Saajan]

In polymer's official page , in "using elements" section there is a ajax example. i guess the polymer-ajax is mentioned ,which as i know has been changed to core-ajax.

@ebidel might know what the current status of our docs switching from polymer-* to core-*.

They're all updated in the docs repo: https://github.com/Polymer/docs/blob/master/docs/start/usingelements.md

We'll hopefully push the site this week :)
