Classes that support memory usage reporting should provide
void reportMemoryUsage(MemoryObjectInfo*) const;
method. If such method is present we should invoke it to collect
memory usage data, otherwise we should just count sizeof the class.
The method detection can be automated at compile time using using
template trick called SFINAE(http://en.wikipedia.org/wiki/Substitution_failure_is_not_an_error).
