feat(log): Log information as program runs

This commit does a few things: - Sets up the ability to log information based off log level - Figures out where to log the file - Starts logging information in the program As this is a first pass the logging is good enough to know where things went wrong, but we can expand on this in the future to log many many things. We just now have an initial implementation. The log is written out to a file that can be read by the user if they pass in -v, -vv, etc. where each v is an extra level of logging.
