Detailed Description

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.
