 Usage    : n/a
 Function : Rearranges named parameters to requested order.
 Returns  : @params - an array of parameters in the requested order.
 Argument : $order : a reference to an array which describes the desired
                     order of the named parameters.
            @param : an array of parameters, either as a list (in
                     which case the function simply returns the list),
                     or as an associative array (in which case the
                     function sorts the values according to @{$order}
                     and returns that new array.

 Exceptions : carps if a non-recognised parameter is sent
