Interpolate the object to another grid, using CDO
References : https://code.zmaw.de/projects/cdo/embedded/1.6.4/cdo.html#x1-5200002.12.1
Provider / contact : climaf at meteo dot fr
Output : the interpolated object
Climaf call example
>>> ds= .... #some dataset, with whatever variable
>>> remapbil_ds=regridn(ds,cdogrid="r180x90") # Target Grid is 2°x2° - interpolation is bilinear
>>> remapcon2_ds=regridn(ds,cdogrid="n127", option="remapcon2") # Target Grid is Gaussian - interpolation is 2nd order conservative
Side effects : None
Implementation : standard CDO calls (remapgrid)
