regrid.py

This file contains useful functions for regridding.

This is usually a two step process:

1. Read the source and destination grids in using the GRID class.
2. Make a regridder using make_regridder to regrid from source GRID to destination GRID.
3. Pass regrid_data the regridder and data on the same grid as the source GRID.

You can now save the regridded data as a netcdf, and pass this as an option to regrid_data.
