// pEpLog
// ======
// a "to be kept ultra small and simple" logging unit.
// featuring:
// * Logging macros that completely eliminate any logging calls in release-builds (NDEBUG)
// * thread safe (no interleave when logging from diff threads) TODO: pEpLogger: REALLY?
// * OS dependent backend switches:
// * android: __android_log_print
// * all other OS: cerr
// * Logging without any class/object (pEpLog / pEpLogRaw macros)
// * runtime switchable (on/off) only on a global level
// * Class backed Logging macros (pEpLogClass / pEpLogClassRaw)
// * * runtime switchable (on/off) on a class and object level
//
// There are already too many features and you might want even more and more.
// But the feature-policy of this logging unit is very restrictive, and there is a
// primary design goal to keep it very simple, maintainable and portable.
//
// pEpLog - logformat "thread - __FILE__::__FUNTION__ - <message>"
