/**
* SpecialPage: handling special pages and lists thereof.
*
* To add a special page in an extension, add to $wgSpecialPages either
* an object instance or an array containing the name and constructor
* parameters. The latter is preferred for performance reasons.
*
* The object instantiated must be either an instance of SpecialPage or a
* sub-class thereof. It must have an execute() method, which sends the HTML
* for the special page to $wgOut. The parent class has an execute() method
* which distributes the call to the historical global functions. Additionally,
* execute() also checks if the user has the necessary access privileges
* and bails out if not.
*
* To add a core special page, use the similar static list in
* SpecialPage::$mList. To remove a core static special page at runtime, use
* a SpecialPage_initList hook.
