/*
	session logger

	sample:
	#include "log.h" (or slog.h)
	slog << logerror << "message" << "something" << logend;
	slog << logwarning << T("message_to_translate") << x << logend;

	if the latter example "message_to_translate" will be taken from locales
	currently following manipulators are taken into account:
		loginfo    - the message in a normal info
		logwarning - this is a warning
		logerror   - this is an error
		logend     - end of a line -- we have one kind of a message (info, warning, error) per line

	loginfo, logwarning, logerror should be specified at the beginning of a line
	(other manipulators are skipped)
