  13  * Purpose: implements methods of "template" class declared in               *
  14  *          DECLARE_OBJARRAY macro and which couldn't be implemented inline  *
  15  *          (because they need the full definition of type T in scope)       *
  16  *                                                                           *
  17  * Usage:   1) #include dynarray.h                                           *
  18  *          2) WX_DECLARE_OBJARRAY                                           *
  19  *          3) #include arrimpl.cpp                                          *
