//       Class : MemoryUsagePointerCounts
// Description : This is a supporting class for MemoryUsage.  It
//               tracks the relative counts of a number of pointers of
//               some type (or age), for use by TypeHistogram and
//               AgeHistogram.  It's not exported from the DLL, and it
//               doesn't even exist if we're compiling NDEBUG.
