A tool to be eventually used for getting a smarter diff for various file types.

Smartdiff can be used via the git-difftool command. You can follow these steps to use it, although it is still very rough around the edges:

1. Clone the repository, and run cargo build inside it. If you do not have cargo, you need to install it.
2. The binary will be located within target/debug.
3. Add the path to that target/debug to your PATH variable.
4. Go to a Git repository that has an unstaged change to a JSON file, and run: git smartdiff.

That should do it, although it doesn't do much for now.
