Here are a few more thoughts about how we will implement a pre-commit hook:

1. Have a less verbose logging scheme and only show what is causing the issue
2. Can throw a nonzero exit code so pre-commit can fail when discovering secrets. We already support this
3. Have a way to dump the findings to JSON
4. Can point out what is causing the pre-commit fail. For example, if we discover an AWS credential, it would be nice to show what file, pattern, and regex match is causing the issue. Related to #61
5. The PC hook should also allow filtering signatures we need (which we already have) and specifying signatures we want to ignore (which we don't have).
