	/**
	 * a structured array of links usually used for the tabs in a skin
	 *
	 * There are 4 standard sections
	 * namespaces: Used for namespace tabs like special, page, and talk namespaces
	 * views: Used for primary page views like read, edit, history
	 * actions: Used for most extra page actions like deletion, protection, etc...
	 * variants: Used to list the language variants for the page
	 *
	 * Each section's value is a key/value array of links for that section.
	 * The links themselves have these common keys:
	 * - class: The css classes to apply to the tab
	 * - text: The text to display on the tab
	 * - href: The href for the tab to point to
	 * - rel: An optional rel= for the tab's link
	 * - redundant: If true the tab will be dropped in skins using content_actions
	 *   this is useful for tabs like "Read" which only have meaning in skins that
	 *   take special meaning from the grouped structure of content_navigation
	 *
	 * Views also have an extra key which can be used:
	 * - primary: If this is not true skins like vector may try to hide the tab
	 *            when the user has limited space in their browser window
	 *
	 * content_navigation using code also expects these ids to be present on the
	 * links, however these are usually automatically generated by SkinTemplate
	 * itself and are not necessary when using a hook. The only things these may
	 * matter to are people modifying content_navigation after it's initial creation:
	 * - id: A "preferred" id, most skins are best off outputting this preferred
	 *   id for best compatibility.
	 * - tooltiponly: This is set to true for some tabs in cases where the system
	 *   believes that the accesskey should not be added to the tab.
