/*
LOG_ctl.h

# Depends on:
- defaults.h
- SD_card.h

# Description:
- This header contains the implementation of a logger, which is a singleton with mutex to make sure Serial and other stuff
don't overlap. It'll create a log.txt on the SD card, if any is found. It won't check for SD card write failures.
