<dd><p>Test if the object has been freed by the game engine and is no longer valid.</p>
<p>Normally this is not a problem but when storing game engine data in the GameLogic module,
KX_Scenes or other KX_GameObjects its possible to hold a reference to invalid data.
Calling an attribute or method on an invalid object will raise a SystemError.</p>
<p>The invalid attribute allows testing for this case without exception handling.</p>
