Documentation is missing

[jscissr]

There is no documentation on how to use this package, and also no documentation telling that it exists at all. I found this stackoverflow question (and answered it), there you can see a way to use this package.

FWIW, you also need to add the font files themselves into polymer.json....if you're using polymer-cli that is.

Created this simple documentation on this pull request. https://github.com/PolymerElements/font-roboto-local/pull/10

Should get the job done.
