+ * Purpose: implements methods of "template" class declared in DECLARE_LIST  *
+ *          macro and which couldn't be implemented inline (because they     *
+ *          need the full definition of type T in scope)                     *
+ *                                                                           *
+ * Usage:   1) #include dynarray.h                                           *
+ *          2) WX_DECLARE_LIST                                               *
+ *          3) #include listimpl.cpp                                         *
+ *          4) WX_DEFINE_LIST                                                *
