namespace love
	* Superclass for all object that should be able to  cross the Lua/C border
	* (this pertains to most objects).
	* This class is an alternative to using smart pointers; it contains retain/release
	* methods, and will delete itself with the reference count hits zero. The wrapper
	* code assumes that all userdata inherits from this class.
	class Object

		// The reference count.
		int count;


		* Constructor. Sets reference count to one.

		* Destructor.
		virtual ~Object() = 0;

		* Gets the reference count of this Object.
		* @returns The reference count.
		int getReferenceCount() const;

		* Retains the Object, i.e. increases the
		* reference count by one.
		void retain();

		* Releases one reference to the Object, i.e. decrements the
		* reference count by one, and potentially deletes the Object
		* if there are no more references.
		void release();
