Title: Make tooltip examples accessible

This is a temporary accessibility fix for ``. Because of an outstanding accessibility issue with `` (https://github.com/angular/material/issues/427), `` components used in conjunction with `` do not have accessible names and are read aloud in a screen reader simply as "button".

The current fix is to add `aria-label` to the parent button element, but the ideal solution would be to require `` to label itself.
