Detailed Description

template<class T>
class COM_ptr< T >

COM_ptr<T>: smart pointer to automatically de-reference COM objects.

This object is NOT (automatically) threadsafe. We are calling IUnknown::AddRef()/Release() on an object, so this pointer is only as threadsafe as the underlying COM object. However, because the object maintains its own count, this pointer is safe to use in collections.
Semantics of this pointer:

• Any raw interface pointer passed will be assumed to already have a reference taken, so AddRef() will not be called again.
• Assigning from another COM_ptr<T> will take another AddRef()
