-  Provides allocation checking for heap memory for C++.  This is used as a

-  really need to deal with this class directly; it is hooked in automatically
-  unless the ENABLE_MEMORY_HOOK macro is defined.  Generally, release builds
-  should not have this enabled, since it will slow things down tremendously.
-  NOTE: this object can absolutely not be hooked into callstack tracker, since
-  this object implements all c++ memory, including the tracker's.  This object
-  will use the backtrace information if it's available.
