! Writes history in netCDF format
!
! authors Tony Craig and Bruce Briegleb, NCAR
! Elizabeth C. Hunke and William H. Lipscomb, LANL
! C. M. Bitz, UW
!
! 2004 WHL: Block structure added
! 2006 ECH: Accepted some CCSM code into mainstream CICE
! Added ice_present, aicen, vicen; removed aice1...10, vice1...1.
! Added histfreq_n and histfreq='h' options, removed histfreq='w'
! Converted to free source form (F90)
! Added option for binary output instead of netCDF
! 2009 D Bailey and ECH: Generalized for multiple frequency output
! 2010 Alison McLaren and ECH: Added 3D capability
! 2013 ECH split from ice_history.F90
