33    /** This class is designed to be subclassed by OGRE users, to allow them to
34        associate their own application objects with MovableObject instances
35        in the engine.
36    @remarks
37        It's always been suggested that an OGRE application would likley comprise
38        a number of game objects which would keep pointers to OGRE objects in order
39        to maintain the link. However, in some cases it would be very useful to be able to
40        navigate directly from an OGRE instance back to a custom application object.
41        This abstract class exists for this purpose; MovableObjects hold a pointer to
42        a UserDefinedObject instance, which application writers subclass in order to
43        include their own attributes. Your game objects themselves may be subclasses of this
44        class, or your subclasses may merely be a link between them.
45    @par
46        Because OGRE never uses instances of this object itself, there is very little
47        definition to this class; the application is expected to add all the detail it wants.
48        However, as a hint, and for debugging purposes, this class does define a 'type id',
49        which it is recommended you use to differentiate between your subclasses,
50        if you have more than one type.

62            OGRE MovableObject instances. Recommend you override this in your classes if you
63            use more than one type of object.
64        @par
65            Alternatively, you can override the getTypeName method and use that instead;
66            that version is a litle more friendly and easier to scope, but obviously
67            slightly less efficient. You choose which you prefer.
