By default, with no `--type` flag specified, container-diff will run Apt package analysis.

To use container-diff to perform a diff analysis on two images, you need two Docker images (in the form of an ID, tarball, or URL from a repo). Once you have those images, you can run any of the following differs:
```
container-diff diff <img1> <img2> [Run all differs]
container-diff diff <img1> <img2> [Run default differs]
container-diff diff <img1> <img2> --type=history [History]
container-diff diff <img1> <img2> --type=file [File System]
container-diff diff <img1> <img2> --type=pip [Pip]
