[ferret_users] Vertical regridding without interpolation

[mcaillau <Matthieu.Caillaud@xxxxxxxxxx>]

Hi Ferret users,

I have data on a vertical level axis (level-grid) and i would like to 
regrid it to a regular z axis.
I have the thickness of each level (which vary in time).

I know that ZAXREPLACE would do it but i dont want my data to be 
interpolated on the z-axis. I am looking for the following 
transformation :
for each grid cell of my z-axis (so at a given depth) it will affect the 
value at the same depth from my level-grid.

Thank in advance for your help

Matthieu
