! !REMARKS:
! If the netCDF4 library is used, then the NF_CLOBBER flag will write
! a classic (i.e. netCDF3) file. Use NF_64_BIT_OFFSET to create a
! netCDF 4 file. (bmy, 11/7/11)
!
! !REVISION HISTORY:
! Initial code.
! 07 Nov 2011 - R. Yantosca - Also give the option to create a netCDF4 file
! by passing the optional WRITE_NC4 argument
