Detailed Description

simple ref counted class to maintain a wxObject* as if it is a smart pointer

If you want to store wxObject pointers in a STL template list ( like a2dlist ), that becomes a problem. STL stores object by value, and does not delete the object pointed to when removing a pointer from the list. The trick is to store a2dSmrtPtr< wxObject> in the list, which will automatically delete wxObject when a smart pointer. But a a2dSmrtPtr< wxObject> can not be created since wxObject has no refcounting as needed for a2dSmrtPtr. Now this class wraps the wxObject into a class which does have the refcounting, so one stores a2dSmrtPtr< a2dRefCount > in the STL list instead, and all will be oke.
