The
SizeOf class tries to determine the size of memory structures.
This is tried by reflection and so on, but if an object is
'SizeMeasurable' then it is asked to the object directly.
So, if your object stores its bulk in private members, and you want
its size to be determined adequately, then you should let it
implement this interface.
If you did not implement a class yourself, but have a clue how to
guess the size anyhow, then you could also put this implementation
in SizeOf itself (as for example was done for String). The
disadvantage of this approach is of course that you don't have
access to private members.
