Interpolate the object to the grid of another object, 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
Mandatory arguments: none
Output : the interpolated object
Climaf call example:
>>> ds= .... # some dataset, with whatever variable
>>> grid_ds= ....# some other dataset, used here for its grid
>>> remapbil_ds=regrid(ds,grid_ds) # Interpolation is bilinear
>>> remapcon2_ds=regridn(ds,grid_ds, option="remapcon2") # Interpolation is 2nd order conservative
Side effects : a temporary file is created in current directory, then erased (name : climaf_tmp_grid)
Implementation : standard CDO calls (griddes and remapgrid)
