Feature Request - Add a new method that returns true, at the first encounter of difference

[azme94]

Request: A method that returns immediately, at the first encounter of difference, without any further difference checks.
bool IsDiff(ob1, obj2)

Justification: Sometimes, the app only cares about if the objects are same or not and then only write the updated full object to DB.

Good idea, I'll look into implementing that on Monday as it would be pretty easy.

I may even through in some performance improvements since I haven't touched this lib in a while
