TIsAProxy(const std::type_info& typ)

 Standard initializing constructor

 Standard destructor

 Set class pointer
   This method is not thread safe

TClass* operator()(const void* obj)

 IsA callback

void* FindSubType(const type_info* ) const

 See if we have already cached the TClass that correspond to this type_info.

void* CacheSubType(const type_info* , TClass* )

 Record the TClass found for a type_info, so that we can retrieved it faster.
