+	 * Used to register a new template pack with the messages system.
+	 *
+	 * Template packs are primarily defined via class extending EE_Messages_Template_Pack and are typically used to
+	 * change entire layouts for a set of message templates.  This method is used to register the new template pack and
+	 * automatically have it loaded in the appropriate places.
+	 *
+	 * This registry also verifies that there isn't already a template pack registered with the same name and if there
+	 * is then it will add an EE_Error notice.
+	 *
+	 * Note that this only handles registering the your Template Pack class with the message template pack system.
+	 * However, there is also a naming schema you must follow for templates you are providing with your template pack.
+	 *
+	 * @param string $identifier The internal reference used to refer to this template pack.  Note, this is first come,
+	 *                           first serve.  If there is already a template pack registered with this name then the
+	 *                           registry will assign a unique reference for it so it can still be activated (but this
+	 *                           makes it harder to deregister as it will be unique per load - so its best to try to
+	 *                           make this a unique string!)
+	 * @param array  $setup_args array {
+	 *                           An array of required values for registering the template pack.
+	 * @type string  $path       The path for the new template pack class.
+	 * @type string  $classname  The name of the new Template Pack Class.
+	 *                           }
