Filering on cartesian grid

[bastorer]

Hi Hemant

Thanks for pointing this out. coarse_grain_scalars default to assuming inputs in degrees and then converting to radians. I forgot to add a flag to turn off that behaviour when running on Cartesian. I'll fix that, but if you pass --is_degrees false when you run the current code, it will disable the conversion [ alternatively you could give the filter scales in radians, but that's probably less pleasant ].

Thanks @bastorer.

In short, to run on a cartesian grid, I need to set CARTESIAN = true while compiling (the rest of the parameters do not change) and pass --is_degrees = false when I execute the coarse_grain_scalars.x file.
