Detailed Description
This class provides reference counting through the methods grab() and drop(). Most objects with the framework are derived from ReferenceCounted, and so they are reference counted.When you create an object within the framework, calling a method which starts with 'create', an object is created, and you get a pointer to the new object. If you no longer need the object, you have to call drop(). This will destroy the object, if grab() was not called in another part of you program, because this part still needs the object. Note, that you only need to call drop() to the object, if you created it, and the method had a 'create' in it.
