/*****************************************************************************
* 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 *
*****************************************************************************/
