136     C is treated as an open-ocean cell
137     C that ice shelf can flow into)
138     C -1=outside computational domain; will not change
139     C

152     C
153     C STREAMICE_vfacemask similar to ufacemask
154     C STREAMICE_ufacemask_bdry field initialized at the beginning of simulation

157     C STREAMICE_vfacemask_bdry CONSTANT FOR A SIMULATION
158     C STREAMICE_calve_mask specified allowed extent of ice shelf
159     C (should be integer, but don't know howvi sre to read ints from file)
