  11
  12     Add-on base class for a trackable object. This class maintains an internal
  13     linked list of classes of type wxTrackerNode and calls OnObjectDestroy() on
  14     them if this object is destroyed. The most common usage is by using the
  15     wxWeakRef<T> class template which automates this. This class has no public
  16     API. Its only use is by deriving another class from it to make it trackable.
