 @fileoverview A view that allows the user to control which single tab is
 displayed.

 We follow a fairly standard web convention of backing our tabs with hidden radio
 buttons but visible radio button labels (the tabs themselves) which toggle the
 input element when clicked. Using hidden radio buttons makes sense, as both tabs
 and radio buttons are input elements that allow user selection through clicking
 and limit users to having one option selected at a time.
