 756          * a structured array of links usually used for the tabs in a skin
 757          *
 758          * There are 4 standard sections
 759          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 760          * views: Used for primary page views like read, edit, history
 761          * actions: Used for most extra page actions like deletion, protection, etc...
 762          * variants: Used to list the language variants for the page
 763          *
 764          * Each section's value is a key/value array of links for that section.
 765          * The links themseves have these common keys:
 766          * - class: The css classes to apply to the tab
 767          * - text: The text to display on the tab
 768          * - href: The href for the tab to point to
 769          * - rel: An optional rel= for the tab's link
 770          * - redundant: If true the tab will be dropped in skins using content_actions
 771          *   this is useful for tabs like "Read" which only have meaning in skins that
 772          *   take special meaning from the grouped structure of content_navigation
 773          *
 774          * Views also have an extra key which can be used:
 775          * - primary: If this is not true skins like vector may try to hide the tab
 776          *            when the user has limited space in their browser window
 777          *
 778          * content_navigation using code also expects these ids to be present on the
 779          * links, however these are usually automatically generated by SkinTemplate
 780          * itself and are not necessary when using a hook. The only things these may
 781          * matter to are people modifying content_navigation after it's initial creation:
 782          * - id: A "preferred" id, most skins are best off outputting this preferred id for best compatibility
 783          * - tooltiponly: This is set to true for some tabs in cases where the system
 784          *                believes that the accesskey should not be added to the tab.
 785          *
 786          * @return array
