   3 Add-on base class for a trackable object. This class maintains
   4 an internal linked list of classes of type wxTrackerNode and
   5 calls OnObjectDestroy() on them if this object is destroyed.
   6 The most common usage is by using the \helpref{wxWeakRef<T>}{wxweakref}
   7 class template which automates this. This class has no public
   8 API. Its only use is by deriving another class from it to
   9 make it trackable.
