    The Sharable class implements a simple reference counting scheme.
    The static Inc() method increments the reference count member.
    The static Dec() method decrements the reference count and deletes
    the object when the reference count becomes zero.

    Other classes may inherit this reference counting behavior simply
    by deriving from this class.
