Ignore this comment - I will open a new issue instead.


was (Author: dmjones500):
The reflection-based builder was never completed. Hence I'm opening this again as a reminder
that it is required.

> 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.
