/* ============================================================
 * NextGen MIS — Tabs (.ng-tabs)
 * ------------------------------------------------------------
 * Horizontal, underline-style tabs. Use `nav ng-tabs` (drop the
 * Bootstrap `.nav-tabs` skin); the `.active` state is still driven
 * by Bootstrap's data-toggle="tab" JS on the <li>, so no extra JS.
 *
 * Wire the full ARIA tab pattern: role="tablist" on the <ul>,
 * role="tab" + aria-controls + aria-selected on each <a>, and
 * role="tabpanel" + aria-labelledby on each pane. The markup sets
 * the initial aria-selected; refinements.js keeps it in sync on
 * switch (BS3 toggles .active but not ARIA).
 *
 *   <ul class="nav ng-tabs" role="tablist">
 *     <li role="presentation" class="active">
 *       <a href="#tab-x" id="tab-x-tab" role="tab" data-toggle="tab"
 *          aria-controls="tab-x" aria-selected="true">…</a>
 *     </li>
 *   </ul>
 *   <div class="tab-content">
 *     <div id="tab-x" class="tab-pane active" role="tabpanel"
 *          aria-labelledby="tab-x-tab">…</div>
 *   </div>
