Define the supported extensions. An extension array has keys 'modules', 'extension', and 'class'. 'modules' is an array of PHP module names which the loading code will attempt to load. These values will be suffixed with a library file extension (e.g. ".so"). 'extension' is the name of a PHP extension which will be tested before 'modules' are loaded. 'class' is the string name of a Auth_OpenID_MathWrapper subclass which should be instantiated if a given extension is present.
You can define new math library implementations and add them to this array.
