// A JavaScript class to drop the focus on links in Internet Explorer

// Internet Explorer doesn't understand the CSS outline attributes,
// so this code drops the focus off clicked links to remove the ugly
// outline. It only does this when the browser is detected as being
// Internet Explorer (or a close clone)
