Subject: [PATCH 2/4] Modifications needed to run mpas-seaice column physics in
 ocean model

Add sea ice shared and analysis member directories to make
Divide sea ice Registry file into subfiles
Add sea ice analysis members to ocean model for column seaice option
Add sea ice initialization post initial clock advance
Add seaice_column_reinitialize_fluxes and ocn_seaice_finalize
Update sea ice makefile in mpas-ocean
Add additional sea ice initialization routines
Add sea ice time stepping routines
Add sea ice finalize routines
Add seaice_ prefix to sea ice subroutines used in mpas-ocean that need it
Renamed sea ice pools and fields to avoid duplication with ocean model: regionNamesSeaice, column_diagnostics, nRegionsSeaice, regionsPool, regionCellMasks, seaice_tracers
Put sea ice package set up in include file for use in ocean model
Moved reinitialization of transport diagnostics to transport module
Made the time step a subroutine argument rather than namelist config in sea ice column physics so can be called from ocean model
Divided up seaice_column_update_state between transport and column physics
Refactored sea ice forcing for use in ocean model
