Checkpoint on a utility helper class. Basically, if you have a class that you want to count the numbers of instances, you do this:

class Foo
#ifdef TRACK_OBJECT_USAGE
      : public InstanceCounter<Foo>
#endif

Then, use this macro somewhere in the class body:
SUPPORT_OBJECT_ANALYTICS(Foo)

Lastly, add whatever information you want to trace out to the function ObjectAnalytics::DumpStatistics().

Here's a sample of the output of what I've instrumented so far:

-----------------------------------------------------------

CardPrimitive current count: 7899
CardPrimitive current byte usage: 2053740
