The world's simplest AngularJS tab control

Here is a very simple tab control - created using AngularJS - with literally just one line of javascript code - a scope variable bound to the page.

I had originally scoured the web for a bootstrap or other tab control available, but after playing around with some HTML & Angular, I came up with this simple, functional control: 1 line of JS, 2 css selectors and 4 divs.
