Memory management
    All objects, which expose interfaces, maintain internally an integer value called reference count. The reference count is 
    incremented when an interface has been queried from the object or another object inside the software stores a reference to it. 
    The reference count is decremented when an interface or reference is released. A reference-counted object is only deleted 
    from memory during a release operation when its reference count becomes zero 
    
        In most situation the reference counting is maintained internally by DG Kernel and should not be modified. 
        Sometimes, often when normal flow of execution was interrupted by an exception, the reference count can become incorrect 
        and the object can be over-released and prematurely deleted, which often causes an exception.  
        On the other hand, reference count being incorrectly greater than the actual number of users, causes a memory leak. 
           In either situation please report the problem 
    
        The reference counting can be checked using IGlobalAPI_KC.GetRefernceCount() method.
