The CXAutoReference templated class allows reference-counted objects to be passed around while automatically maintaining the correct reference count. This is a very simple and powerful tool to use for resource management. The referenced object must expose a specific reference counting interface- typically this is achieved by inheriting from DynamicReferenceCount but other techniques are permitted.
CXAutoReference<T> is designed to act in a manner syntactically equivalent to T* where possible.
