 * Warning: remove LOG_LEVEL_* defines in production for major power savings.
 *
 * Defining a log level will set up a serial connection to use for logging.
 * This serial connection sets up a timer prohibiting the mbed chip
 * from entering low power states, drawing ~1.4mAh instead of ~20µAh with logging disabled.
