/**
 * Directive to show a notification.
 *
 * Note: using this directive is preferred over the Notification class (which uses jquery
 * exclusively).
 *
 * Supports the following attributes:
 *
 * * **context**: Either 'success', 'error', 'info', 'warning'
 * * **type**: Either 'toast', 'persistent', 'transient'
 * * **noclear**: If truthy, no clear button is displayed. For persistent notifications, has no effect.
 *
 * Usage:
 *
 *     <div piwik-notification context="success" type="persistent" noclear="true">
 *         <strong>Info: </strong>My notification message.
 *     </div>
