Greetings!

   I am just about to start doing some work with Modeling, and I'm very 
excited about its capabilities! It looks very promising, to say the least.

   One question I have is on what "willChange" actually does. As I 
understand it, Modeling captures a single "snapshot" of some fetched rows 
(objects), and whenever "willChange" is called on a particular object's 
attribute, that attribute is made "dirty", such that when "ec.saveChanges()" 
is called, only "dirty" attributes get updated. Is this accurate?

   Thanks in advance for any insight.

~Tom
