Save a custom menu.

Parameters

$menu: An array representing a custom menu:

• menu_name: The unique name of the custom menu (composed of lowercase letters, numbers, and hyphens).
• title: The human readable menu title.
• description: The custom menu description.

Modules should always pass a fully populated $menu when saving a custom menu, so other modules are able to output proper status or watchdog messages.
