Really simple example of abstracts - creating an "extension" of AnchorElement with a custom constructor. Uses all inline code, and shows how implicit casts can be used when interacting with API that expects the underlying type.

List of all Sitespeed 4.0 metrics. I couldn't find this list anywhere, and it took me a while to figure out how to generate the file using grunt-sitespeedio (for future reference: set `sitespeedio.default.options.metrics.list=true`). I figure pasting this here will help some other poor souls thanks to the SEO goodness.
