       The base class for all reference counted objects.

       If multiple inheritance is used, RefCount must be virtually inherited from, otherwise references to
       invalid memory will likely result.

       Reference counting information is usually maintained by smart pointer classes Ref, however this mechanism
       can be supplemented or replaced by directly using the public interface to RefCount.

       The unmanage() member is only needed for special cases where memory management must be turned off. For
       example, if a reference counted object is created on the stack, memory management mechanisms based on
       reference counting must be prohibited from deleting it. The unmanage() member accomplishes this, but a
       better solution would be to allocate the object on the heap with new and let a smart pointer manage the
       memory for the object.

       When using a debugger to look at reference counted objects the count is maintained in the reference_count
       member. However, this member is encoded so that memory overwrites can be sometimes detected. Thus,
       interpretation of reference_count is not always straightforward.

voidsc::RefCount::unmanage()[inline]
       Turn off the reference counting mechanism for this object. The value returned by nreference() will always
       be 1 after this is called. The ability to unmanage() objects must be turned on at compile time by
       defining REF_MANAGE. There is a slight performance penalty.
