CCountedPtr - simple reference counting smart pointer.
One of the standard ways how to maintain object's lifetime.
See http://ootips.org/yonat/4dev/smart-pointers.html for more general info about smart pointers.
This class implements ref-counted pointer for objects/interfaces that support AddRef() and Release() methods.
