 733          * a structured array of links usually used for the tabs in a skin
 734          *
 735          * There are 4 standard sections
 736          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 737          * views: Used for primary page views like read, edit, history
 738          * actions: Used for most extra page actions like deletion, protection, etc...
 739          * variants: Used to list the language variants for the page
 740          *
 741          * Each section's value is a key/value array of links for that section.
 742          * The links themseves have these common keys:
 743          * - class: The css classes to apply to the tab
 744          * - text: The text to display on the tab
 745          * - href: The href for the tab to point to
 746          * - rel: An optional rel= for the tab's link
 747          * - redundant: If true the tab will be dropped in skins using content_actions
 748          *   this is useful for tabs like "Read" which only have meaning in skins that
 749          *   take special meaning from the grouped structure of content_navigation
 750          *
 751          * Views also have an extra key which can be used:
 752          * - primary: If this is not true skins like vector may try to hide the tab
 753          *            when the user has limited space in their browser window
 754          *
 755          * content_navigation using code also expects these ids to be present on the
 756          * links, however these are usually automatically generated by SkinTemplate
 757          * itself and are not necessary when using a hook. The only things these may
 758          * matter to are people modifying content_navigation after it's initial creation:
 759          * - id: A "preferred" id, most skins are best off outputting this preferred id for best compatibility
 760          * - tooltiponly: This is set to true for some tabs in cases where the system
 761          *                believes that the accesskey should not be added to the tab.
 762          *
 763          * @return array
