 770          * a structured array of links usually used for the tabs in a skin
 771          *
 772          * There are 4 standard sections
 773          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 774          * views: Used for primary page views like read, edit, history
 775          * actions: Used for most extra page actions like deletion, protection, etc...
 776          * variants: Used to list the language variants for the page
 777          *
 778          * Each section's value is a key/value array of links for that section.
 779          * The links themseves have these common keys:
 780          * - class: The css classes to apply to the tab
 781          * - text: The text to display on the tab
 782          * - href: The href for the tab to point to
 783          * - rel: An optional rel= for the tab's link
 784          * - redundant: If true the tab will be dropped in skins using content_actions
 785          *   this is useful for tabs like "Read" which only have meaning in skins that
 786          *   take special meaning from the grouped structure of content_navigation
 787          *
 788          * Views also have an extra key which can be used:
 789          * - primary: If this is not true skins like vector may try to hide the tab
 790          *            when the user has limited space in their browser window
 791          *
 792          * content_navigation using code also expects these ids to be present on the
 793          * links, however these are usually automatically generated by SkinTemplate
 794          * itself and are not necessary when using a hook. The only things these may
 795          * matter to are people modifying content_navigation after it's initial creation:
 796          * - id: A "preferred" id, most skins are best off outputting this preferred id for best compatibility
 797          * - tooltiponly: This is set to true for some tabs in cases where the system
 798          *                believes that the accesskey should not be added to the tab.
 799          *
