[MITgcm-support] Restarting the MITgcm

Problem solved. I set the model to produce the permanent checkpoint 
files, so I don't need to fiddle with the rolling restart files - The 
problem was probably that I miscounted the number of 0's in the file 
name when renaming the rolling checkpoint files, or something silly like 
that...

Thanks for all your suggestions. It is working now!
