Decide on capitalization of private static final fields

[SIMULATAN]

At the moment, there are some private static final fields that are written in lower case, and others are upper case.
We should decide on either convention and update the whole code accordingly.

Another thing that should be factored into considerations: loggers, do we call them LOGGER, logger, log, or something else?

Please provide your opinions on what we should settle on!
