Setting up for better resiliency

- Generalized the config a bit more
- Added the start of the the circuit breaker and its configuration
Stable point
Documenting

- Needed to be done... doesn't mean I'm finished but it felt good to do.
Making use of heroku config vars
Adding some more rudiments
Adding some debugging for DB connections
local script needs ignoring
Still trying to get postgres JDBC to work
A bit of refactoring and some tests

- Tests make me a bit more comfortable
- Refactoring moves the database work around a little bit
  - It's still not the type of DB abstraction I might want, but it's a bit
    better in the way it's organized
Added debugging, circuit breaker, and comments

- The Circuit Breaker has always been there, but now it's actually wired in.
- Added some debugging to the route so that I can actually understand why
  something doesn't route properly
- Documented an obvious bug (that I'm not fixing yet)
