[MITgcm-support] (Fixed) spatially varying viscosity

[Matthew Mazloff]

Hi Christopher,

I know that the viscosity coefficients are 3-D, so even if  
initializing the values from a file has not been implemented you  
should be able to implement it fairly easily.  (you could probably  
use the code that initializes a restoring time-scale from file  
lambdaThetaFile as a template)
