  Circle Menu Component

/**
 * This is the actual menu component. It consists of a menu element with an
 * unordered list inside, and also a button to toggle the actual menu.
 * It's fixed to the bottom-right of the screen, and each of the items are
 * positioned absolutely inside the parent menu tag. The default set up above is
 * 5 menu items. Because all the transforms and such are calculated wrt
 * this number, you'll need to edit it accordingly depending on how many items
 * you decide to put in the markup.
 *
 * Example markup:
 *
 * <menu class="c-circle-menu">
 *   <ul class="c-circle-menu__items">
 *     <li class="c-circle-menu__item">
 *       <a class="c-circle-menu__link"></a>
 *     </li>
 *     <li class="c-circle-menu__item">
 *       <a class="c-circle-menu__link"></a>
 *     </li>
 *     ...
 *   </ul>
 * </menu>
