Syntax in code :
----------------

  function names starting by "hook_" are hooks called that way:

global $hooks;
$res=$hooks->invoke("hook_class_method_name",array($param1,$param2));

$params1 & 2 are sent as parameters to the hooked functions of each files.

the hook function name must have the CALLING class name after hook_ 
like hook_admin_del_member for a hook in "admin" class.

$res is an array with the returned data as values, for each function called in a class. 
The key in that array is the classname called.
