Regridding

The coecms regridder makes use of CDO to generate its regridding weights.

Effectively behind the scenes it runs:

cdo genbil,gridspec sourcegrid.nc weights.nc
cdo remap,gridspec,weights.nc source.nc dest.nc

with some added Dask magic.

There are two ways to run the regridder. You can create a coecms.regrid.Regridder, which stores the weights for re-use, or you can call coecms.regrid.regrid() to quickly regrid a single dataset.
