			* 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.
