Detailed Description

Logger.h - allowing logs with more control.

next are codes for libraries sections using Logger
Application codes should use LOG_APP as the LOCAL_SECTION code
each c file using the logger should contain at top something like:
#include "Logger/Logger/Logger.h"
#define LOCAL_SECTION LOG_APP
#define LOCAL_LEVEL LOG_DEF_LEVEL
extern MedLogger global_logger;

specific sections should use the section code instead of LOG_APP .
LOCAL_LEVEL can be changed to something else to allow more or less verbal logs.

Macro Definition Documentation

NO_LOG_LEVEL

#define NO_LOG_LEVEL   0

logs get printed if their given level (which can be different for different code sections)
is > log level in levels.

this means that min level never be printed, and max level is always printed
