As I was wrapping my head around the project it wasn't very obvious to me what the high level
structures of the project where (for example - what are the most important words?) These two
docs try to provide what I think I probably would have appreciated when I started digging in.
The two docs are:
* docs/process_flow.md - Gives a high level overview of how trufflehog injests and processes
sources
* docs/concurrency.md - Tries to give a big picture overview of the concurrency structure that
trufflehog uses, including the primary channels
Also added a couple quick links from likely jumping off points in existing docs/code
