C     !ROUTINE: MNC_INIT

C     !INTERFACE:
      SUBROUTINE MNC_INIT( myThid )

C     !DESCRIPTION:
C     Initialize (zero) the look-up tables.  This routine should
C     \textbf{always} be run before any other MNC subroutines to ensure
C     that the lookup tables start in a well-defined state.
      
C     !USES:
#include "mnc_common.h"

C     !INPUT PARAMETERS:
      integer myThid
CEOP

C     !LOCAL VARIABLES:
      integer i,j, g, v
      character blank*(MNC_MAX_CHAR)
