Demo not loading dependencies over https

[STRML]

Some browsers seem to be pinning github.io to https - likely a recent use of HSTS. Since your scripts are not loaded over HTTPS, modern browsers will refuse to load them and the demo shows a blank white page.

You can fix this by simply changing the scripts to be protocol-agnostic (starting with // instead of http:// or https://).

Thanks! Will do :)
I will update the example to include Brushing today, too.
