vb_set_verbose

 Put verbose level into VBMEG environment (global) variable 'vbmeg_inst'

 This function is used to control if messages in VBMEG are shown or
 not. It is noted that the verbose level is supported by vb_disp and
 other display functions (e.g., fprintf) is not affected with the
 verbose level. 

 [syntax]

 [input]
 verbose_level: <<string>> Verbose level string
   'NONE'      Suppressing all messages 
   'EMERGENCY'
   'WARNING'
   'NOTICE'    VBMEG default value
   'INFO'
   'DEBUG'     Displaying all messages
