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

Browse Source 
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:

-----------------------------------------------------------
Object Usage Stats

CardPrimitive current count: 7899
CardPrimitive current byte usage: 2053740
CardPrimitive max count: 7908
CardPrimitive max byte usage: 2056080

MTGCard current count: 13973
MTGCard current byte usage: 670704
MTGCard max count: 13982
MTGCard max byte usage: 671136

MTGCardInstance current count: 180
MTGCardInstance current byte usage: 172080
MTGCardInstance max count: 189
MTGCardInstance max byte usage: 180684
