[gradsusr] two-dimensional (R-Z) data files

[James Potemra]

Hi Sim,

In the data descriptor file you don't list any variables as having a 
depth component.  For example,

azimtemp            0  11,100,0 ** (profile) Temp. [K]

That first "0" means there are only surface values for this variable.  I 
think you want that to be "24"
