More detailed error reporting

I've got my own home grown tool for diffing directories but I'd much have a reusable crate.

API Ideas:

• Enum of LeftExists, RightExists, BothExist(Option<Difference>)
• diff_dir_list(path, path) provides an iterator of (path, enum(None))
  • doesn't do content diffing allowing people to do custom solutions for Will fail on large files #6
• diff_dir(path, path) provides an iterator of (path, enum)
  • Take advantage of difference like [assert_cli](
• assert_dir_eq!
  • provides a default policy for failing (whether it be panic on first failure or summarize the all differences)

Hey @epage ! I'm not really working on dir-diff these days, but if you want to hack on it, I'd be happy to give you commit rights, etc 👍

That works.

Any vision or implementation goals you had that you'd like me to maintain with my changes?

Not specifically; I had originally created this library as a way of doing testing; you could have a fixture with the directories you planned on creating, run the tests, and diff them. I'm open to whatever though. Adding you as a collaborator right now!
