// Sharable.h
//
// 	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.
