Adding documentation in the README
More documentation updates
Decided to push the program as-is.  I removed the IOS versions we're using for
security reasons, but I left the regex as examples of how things work.

Without a config file it's hard to maintain two different copies, one for
public release and one for the office, but I hope to keep porting the changes
between the two so if I improve it I should be able to make it public.
