C !ROUTINE: DIAGNOSTICS_SWITCH_ONOFF
C !INTERFACE:
SUBROUTINE DIAGNOSTICS_SWITCH_ONOFF( myTime, myIter, myThid )
C !DESCRIPTION:
C-----
C Called at the beginning of the time-step,
C to switch on/off diagnostics for snap-shot output
C-----
C during iterations that are multiple of |freq|,
C switch ON diagnostics (ndiag>=0) that will become active
C and then can be written at the end of the time-step ;
C otherwise, put diagnostics in non-active mode (ndiag=-1)
