/** @class lass::util::CallbackR12
 *  @ingroup Callback
 *  @brief callback with 12 parameter12 and with returnvalue.
 *  @date 2002
 *  @author Bram de Greve [Bramz] (contact: bram@cocamware.com)
 *
 *  It's a single object that can hold a reference to a free function or an
 *  object/(const) method pair.  Once the callback is constructed, it works
 *  completely transparent.  All it shows to the client is a function that
 *  takes 12 parameter(s) and gives a returnvalue.
