-------------------------------

    Fix Version/s: 3.1

Putting into 3.1 as there's no backwards compat issues. That said - patches 
welcome :)

> implementation

> The ToStringBuilder and ReflectionToStringBuilder are great tools for 
> everyday development.
> We use them to show all the properties in an object, which comes handy 
> especially for testing.
> However, JUnit with its assertEquals() just outputs the toString() of the two 
> compared objects. For complex objects, this becomes unreadable.
> So, it would be great to have a DifferenceBuilder with a 
> ReflectionDifferenceBuilder implementation to be able to get only the 
> differing properties of two objects. The question is whether the two objects 
> would have to be of the same type or not.
