/*****************************************************************************
 * Purpose: implements methods of "template" class declared in               *
 *          DECLARE_OBJARRAY 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_OBJARRAY                                           *
 *          3) #include arrimpl.cpp                                          *
 *          4) WX_DEFINE_OBJARRAY                                            *
