        	Let us read the logging settings from the file instead of hard coding them over here
        	The name of the config file is pvlogger.ini
        	The format of entries in it is like
        	First entry will decide if the file appender has to be used or error appender will be used.
        	0 -> ErrAppender will be used
        	1 -> File Appender will be used

            Entries after this will decide the module whose logging has to be taken.For example, contents of one sample config file could be
        	1
        	1,2wayEngine
            8,3g324m.h245user
        	(pls note that no space is allowed between loglevel and logger tag)
        	This means, we intend to have logging of level 1 for the module 2wayEngine
        	and of level 8 for the 3g324m h245user on file.
