## Diffing Versions
When you're storing every version of an object, as PaperTrail lets you do, you're almost certainly going to want to diff those versions against each other. However I haven't built a diff method into PaperTrail because I think diffing is best left to dedicated libraries, and also it's hard to come up with a diff method to suit all the different possible use cases.

You might be surprised that PaperTrail doesn't use diffs internally anyway. When I designed PaperTrail I wanted simplicity and robustness so I decided to make each version of an object self-contained. A version stores all of its object's data, not a diff from the previous version.
